Preliminary Operating Instructions 21 of 62 AIP SERVICE NUMBER 1-800-863-3364
Note: When the remote temperature sensing cable is not installed, charging voltages can be
adjusted to compensate based on the internal temperature sensor, which is inside each charger
on the SCR driver board.
8.2.1 REMOTE TEMPERATURE SENSING CABLE INSTALLATION
A charger shipped from the factory will not have this option connected and temperature
compensation will be disabled. With both AC and DC de-energized, follow the procedure below:
1. The remote temperature sensing cable will be in the charger’s shipping carton. Carefully
unpack the cable from its bag and inspect for any cuts in the cable.
2. Place the 3-pin connector of the cable through one of the spare knockouts provided on the
DC side of the enclosure. See SECTION 6.3. Do not place in the same knockout as either
the AC input or DC output wiring. Protect the wire to prevent damage from the sharp edges
of the opening.
3. Connect the 3-pin connector to JP5. Secure the cable to prevent it from being pulled loose.
See FIGURE 10.1.
4. Secure the other end of the cable to a negative battery terminal post in the center of the
battery set.
5. After the installation is finished, connect DC voltage and verify that the display temperature
corresponds to the temperature of the battery. To view the external temperature, refer to
SECTION 11.3.8 of the manual.
6. Enable the Temperature Compensation by going to DC Settings then go to Temperature
Compensation. Default is disabled. Enable it to External (EX) by pressing right twice, refer
to SECTION 11.3.3 of the manual.
7. The charger is ready for service if the charger display shows the proper battery temperature.
8.2.2 REMOVING TEMPERATURE SENSING CABLE
With both AC and DC de-energized, remove connector from JP5. The charger will automatically
detect that there is no external temperature cable and return to temperature compensation
disabled.
8.3 OPTIONAL REMOTE CONTROL PANEL
This option will allow the charger to be controlled remotely from a distance of up to 50-ft. (15m); without
this option the charger would be controlled from the front door panel. Only one control panel can be
connected at a time. The Remote Control Panel is shipped with a 50-ft. (15m) communication cable with
plug-in connectors. The Remote Control Panel can be mounted to a 19-in. (483mm) relay rack or wall
mounted.
8.3.1 REMOTE CONTROL PANEL INSTALLATION
With both AC and DC de-energized, follow the procedure below:
1. If the Remote Control Panel was ordered with the charger as an option, it will be found
packed inside of the carton shipped with the charger. If it was ordered separately as a
service part kit, it will be packaged in its own carton. In either case, carefully unpack the
control panel assembly and inspect for any cuts in the cable or other damage.
2. It will be necessary to connect the remote control panel printed circuit board to the SCR
driver printed circuit board in the charger. If the remote control panel was ordered as a
service part option and the charger has a control board on the door then the Control printed
circuit board on the door will have to be disconnected before installing the Remote Control
Panel. Only one control printed circuit board can be electrically connected to the SCR Driver
board at a time.
3. Determine where and how the Remote Control Panel will be mounted. The Control Panel is
shipped from the factory with the communication cable entering the bottom of the case. If
preferred by the installer, the cable can be changed to enter the back of the case.
4. To change where the cable enters, remove the four nuts on the case cover to open the case.
Disconnect the cable from the control board, being careful to squeeze the retaining latch on
the cable connector before pulling on the connector. If the latch has been properly released,
