They may be different on the system or the subrackâs terminals. - 7 - 5 CHARGING MODES The ACM1D provides 4 different charging modes : 5.1 Direct mode In this mode, regulation is performed to reach an user-defined level. There is no current limit and no temperature compensation. 5.2 Temperature compensation mode (floating) The DC bus voltage depends on the temperature. The compensation curve has the following equation : V/cell = K1 + K2 t + K3 t2 K1/K2/K3 coefficients are configurable parameters. Temperature compensation 2,15 2,2 2,25 2,3 2,35 2,4 -10 0 10 20 30 40 50 60t (°C) V/ ce ll The temperature range for compensation can also be configured (0°C/32°F to 45°C/113°F in the above example). In this mode, the charging current is limited to an user-defined level. - 8 - 5.3 Temperature compensation (floating) + boost charge mode This mode is identical to the previous one with an additionnal âboost chargeâ mode. temp. compensation + boost charge 2,15 2,2 2,25 2,3 2,35 2,4 -10 0 10 20 30 40 50 60t (°C) V/ ce ll The boost charge voltage level is fixed (not temperature compensated) and programmable. Conditions to enter the boost charge mode are : · Return of the mains supply · At regular interval (can be inhibited) · Manually with the local keyboard or through the communication protocol Conditions to quit the boost charge mode are : · Battery charging current below a programmable threshold. · Manual release by the keyboard or the communication link. · Time-out (programmable) : abnormal condition with alarm. · Mains failure · Abnormal conditions : Disconnection of the battery (Fuse blown, â¦.), loss of a sensor. A charging current limit is applied in floating and boost charge mode (2 different programmable values). - 9 - 5.4 2-rate mode In this mode, the ACM1D has 2 fixed voltage levels : · Float level (low rate : programmable). · Boost level (high rate : programmable). 2 rates mode 2 2,1 2,2 2,3 2,4 2,5 -15 -5 5 15 25 35 45 55 65 Temp (°C) V/ ce ll Conditions to enter in boost charge mode are : · Return of the mains supply · At regular interval (can be inhibited) · Manually by the keyboard or through the communication protocol Conditions to exit the boost charge mode are : · Battery charging current below a programmable threshold. · Manual release by the keyboard or the communication link. · Time-out (programmable) : abnormal condition. · Mains failure · Abnormal conditions : Disconnection of the battery (Fuse blown, â¦.), loss of a sensor. - 10 - 6 BATTERY TEST 6.1 Principle The ACM1D can perform a battery test at regular intervals. Such a test can also be manually triggered. During a battery test, the ACM1D decreases the DC bus voltage so that the battery discharges at a constant current (configurable). The test will stop when the voltage has decreased of a pre-defined value (since the beginning of the test). The duration of the test (from the beginning to the test end) is compared to a nominal duration. The result is stored in the history and an alarm is raised if the battery test failed (test duration is too short). test 1 and 2 start D V T test1 end test2 end time Vbatt Conditions to enter the battery test mode are : · Periodically (can be inhibited) · Manually triggered from the communication protocol or the keyboard. Conditions to exit from the battery test mode are : · Battery voltage dropped of the pre-defined value (test performed to the end). In this case, the battery test duration is kept in the history. · Test is manually stopped (local keyboard or communication protocol). · Mains failure occured during the test : test is aborted. · Current flowing in the load is is too low to continue the battery test. The test is aborted. · Battery is disconnected from the DC bus (fuse blown, LVD open) : The test is aborted. · Regulation gets out of limits (2V..8V) : test is aborted. 6.2 Security When a periodical battery test must be launched, some conditions are checked. If conditions are not met, the test is post-poned by 24 hours. The conditions are : · Load current is high enough to start a battery test. · Battery is connected (fuse is OK, LVD is closed). · No mains failure. · Sensors are not faulty. · Battery charging current is not too high (below an user-defined level). - 11 - 6.3 History management The history is stored in the non-volatile memory. Recorded information is : · Duration of last test. · Duration of previous test. · Duration of longest test. · Number of tests completed to the end. · Number of tests delayed. · Number of tests aborted. All this data can be retrieved from the communication protocol. The history test can be flushed. - 12 - 7 RECTIFIER MANAGEMENT The ACM1D provides a plug and play functionnality for the rectifiers detection. Rectifiers are sensed from the Rect1 to Rect5 inputs (and Rect6 to Rect10 if configured as rectifier inputs). The ACM1D dynamically stores the maximum of rectifiers detected in the non-volatile memory. Therefore : · If a new rectifier is inserted in the system (in a free slot), it will be automatically taken into account in the stored configuration. · If one ore more rectifiers are removed from the system, the ACM1D will compare this configuration to the maximum configuration and raise the «1 rectifier failed» and «more than 1 rectifier failed» alarms. The user has the ability to freeze this new configuration so that the actual rectifiers configuration is stored as the maximum configuration (thus clearing the rectifiers failed alarms). · The rectifiers configuration is persistent after a power-down of the ACM1D. 8 ALARMS AND STATUS MANAGEMENT The ACM1D internally manages 30 alarms and 2 statuses. The alarms and statuses can be reported : · On the local display and the communication protocol. · To the digital ouputs (except the Mains Fail output which is tied by hardware to the Mains Fail input). · To the front panel red LED. The alarms reported on each output can be individually filtered out to allow a very flexible alarm signalling. The following filters are available : · Filter for display · Filter for ALM Urgent output · Filter for ALM Non Urgent output · Filter for Red LED output · Filter for Spare Output 1 · Filter for Spare Output 2 · Filter for Spare Output 3 · Filter for RemoteOff output 8.1 Alarms · 1 rectifier failed · More than 1 rectifier failed These 2 alarms are raised when some rectifiers are missing (compared to the maximum configuration detected by the ACM1D). · Input 1 · Input 2 · Input 3 · Input 4 · Input 5 · Input 6 · Input 7 · Input 8 These alarms are raised when the input is detected as activated (according to the logic defined for each input). · Battery fuse Battery fuse is detected as blown (from FuseBatt input according to the logic of the input). · Load fuse Load fuse is detected as blown (from FuseLoad input according to the logic of the input). · Battery test failed The last battery test duration was below the threshold. · High voltage - 13 - The DC bus voltage is over the defined threshold. · Battery voltage low Battery voltage is below the battery disconnection threshold (LVD batt). · Load cutoff voltage The DC bus voltage is below the non-essential load disconnection threshold. · Battery voltage critical Battery voltage is below a programmable level. · Temperature > temperature threshold 1 Temperature is over a programmable level. · Temperature > temperature threshold 2 Temperature is over a programmabel level. · Regulation error The regulation process does not control the output voltage. · Mains fail Mains fail input is activated. · High rate charge error A high rate charge has been stopped due to a time-out. · Internal error (memory error) Internal non-volatile memory has been corrupted. · Battery on discharge Battery current is over a programmable threshold (and the battery test is not in progress). · Uload Open · Ubatt Open · Ibatt Open(+) · Ibatt Open(-) · Temp Open · Iload Open Analog input fault detection. 8.2 Statuses · High rate charge in progress · Battery test in progress - 14 - 9 FRONT PANEL 9.1 LEDâs 3 LEDâs are provided on the front panel : · Green LED (On) : ACM1D is powered (when flashing, ACM1D is in high-rate charging mode) · Yellow LED (Test) : Battery test in progress. · Red LED (Alarm) : User configurable 9.2 Display 9.2.1 1st line The front panel buttons are used to change the displayed information.

The module can be installed in a 19 or 23 inch standard rack and is held in by 1 front screw. In order to insure EMC The controller must be slotted in a 19 or 23 inch rack, and placed inside a metal cabinet. Input and output cables must be pressed against the metal surfaces of the cabinet and equipped with ferrite beads on the output of the rack. In order to insure electrical safety The rectifier must be placed inside a cabinet providing an electrical, mechanical and fireproof shelter. It is imperative to provide air admissions and outputs to ensure the module natural convection. User & maintenance personnel access must be limited to front panel and to the insulator of solder face. Any work on the module must be carried out by qualified maintenance personnel who are fully acquainted with the specific hazards of electricity and able to take the necessary precautions. Non-authorized persons are absolutely prohibited from handling or working on the module in operation. This module generates high leakage current. The sub-assembly which receives the module must be equipped with a warning label, near the mains connection. The module connections are made through a DIN41612 H96 connector in the rear panel. Check the suitability of the socket connector. This class I (IEC 950) device requires the grounding of the connector row 32. The board may only be connected on a TBTS circuit (in compliance with IEC 950). Internally, no output terminal block is connected to ground. When in operation, the positive polarity may be connected to ground. - 18 - 11 MAINTENANCE This device requires no special maintenance, and is not intended to be repaired on site. When shut down, and for several minutes after module disconnection, hazardous voltages may be present within the module. If the troubleshooting procedures fail to fix your problem, contact our customer service. Adding a power module If a power module is added in the rack, the ACM1D automatically recognises it and lists it in the configuration. Changing a failed power module If a failed power module is changed in the rack it must be replaced at the same position in the rack. Otherwise the system will detect a new module + a failed module in the rack and will raise an alarm. Caution : When removing an ACM1D from the sub-rack, the load and battery relays could be unsupplied so they could open (depending on the subrackâs configuration and relayâs driving logic). In this case, during an ACM1D exchange operation, it is necessary to by-pass the relays manually. - 19 - 12 COMMUNICATION 12.1 Pin assignment of RS232 connector (RJ45) 4 : Gnd 5: Receive (of ACM1D) 6 : Transmit (of ACM1D)8 1 Note : If the cable should be connected to a PC with a DSub9 connector, the wiring is as follows : RJ45-4 DSub9-5 RJ45-5 DSub9-3 RJ45-6 DSub9-2 12.2 Communication Setting Baud rate: 9600 Baud Data length: 8 bit Parity: no parity Stop bit: 1 Flow control: none Local echo mode on terminal side.
