the connector will easily slide out of the socket. Carefully pull the cord and connector out
through the hole in the bottom of the cover. Reinstall the cable through the backside of the
larger hole in the back panel of the case. Reconnect the cable to either one of the connector
sockets on the control printed circuit board. Re-assemble the Remote Control Panel.
5. Carefully route the 50 ft. (15m) long communication cable to the charger making sure it is
protected from being pulled out of the Remote Control Panel or pinched.
6. Place 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 cable to ensure that the sharp edges of the knockout opening
will not damage the cable. Any excess communication cable can be coiled up and wire tied
out of the way.
7. The communication cable can be connected into any of the three RJ1, RJ2 or RJ3 connector
sockets on the charger SCR driver board. Do not connect more than one control board to the
SCR Driver board at the same time.
8. Reconnect the charger to either AC or DC and then verify that the Remote Control Panel is
functioning properly, (refer to SECTION 11). If both charger and remote control panel are
operating normally, they are ready for service.
Important: Proprietary communication protocol is used with the charger and control panel.
Equipment damage will occur if they are connected to Ethernet or any other network device or
port.
8.4 ALARM I/O RELAY BOARD OUTPUT
The optional ALARM I/O Relay board allows the user the use of “NO” (normally open) or “NC” (normally
closed) contacts with reference to “C” (common) to be connected to other equipment for fault detection.
The one GREEN LED and seven RED LEDs are used to signify when each individual relay coil has been
energized. The ALARM I/O Relay board receives its signal to energize the relays from the Charger
Control board.
8.4.1 ALARM I/O RELAY BOARD OPERATION
The GREEN LED (DS1) and J1 contacts are used to indicate the Auxiliary Summary Alarm fault
status. (See FIGURE 8.4.4-2) The GREEN LED will illuminate if the charger detects no faults.
Thirty seconds after any of the monitored faults have occurred, the J1 relay coil will be de-
energized and the GREEN LED will go off.
C=COMMON NC=NORMALLY CLOSED NO=NORMALLY OPEN
The J1 terminal block contacts on the ALARM I/O relay board will switch at the same time as the
Summary Alarm terminal block contacts on the SCR Driver Board. With no faults the relay will be
energized and there will be continuity from “C” to “NC” and no continuity from “C” to “NO” on J1.
With a fault the relay coil will be de-energized and there will be continuity from “C” to “NO” and no
continuity from “C” to “NC”.
The seven RED LEDs and the J2 through J8 terminal block contacts on the ALARM I/O board are
used to indicate the seven individual fault conditions. Each relay will be energized and its
corresponding LED will illuminate when the SCR Driver board detects that fault. When there are
no faults, the relays will be de-energized and there will be continuity from “C” to “NC” and there
will be no continuity from “C” to “NO” on J2 through J8. With a fault, the appropriate relay coil will
be energized and there will be continuity from “C” to “NO” and no continuity from “C” to “NC”. The
appropriate LEDs will illuminate with each fault. See SECTION 11.3.4 for information on setting
up the charger faults. The ALARM I/O relay board terminal blocks and LED indicated fault
functions are shown in FIGURE 8.4.4-2.
