4. Remove nuts, split washers, and flat washers holding
down the battery brackets;
5. Rotate the battery brackets upward to remove it from the
anchoring slots as shown in figure 15.
6. Replace the used battery with the same type gelled lead
acid cell 12V, 7.0 Ah (Ampere-hour).
CAUTION: Dispose of used battery according to local
regulations
!
7. Place new battery in the battery location, as shown in figure 15,
ensuring that the orientation is as, the "+" terminal shown being
the lowest.
8. Install the battery brackets, flat washer, split washers, nuts in this
order and reconnect the wires from the power supply (B) to the
battery (K) ensuring that the red wire connects to the '+' terminal
and the black wire connects to the '-' terminal.
9. Reconnect the power adaptor or turn on the main AC power to
the 660G XT.
NOTE:
For preventive maintenance, the battery back-up should be
replaced every 2 to 3 years, and tested every 6 months by
removing the main AC power.
5.5 New Battery Back-up Installation
Post-installation of the system, if it is decided that the system should
have a battery back-up, order kit 064-511889-K and follow the steps
below.
1. Turn off the main AC power to the 660G XT or disconnect the
power adaptor.
2. Connect the end with the fork crimp terminal of the red wire
supplied with the battery back-up kit to the ‘+’ terminal on the
power supply terminal block BAT. Ensure that the power supply
screw is appropriately tightened to secure the wire.
3. Connect the end with the fork crimp terminal of the black wire
supplied with the battery back-up kit to the ‘-‘ terminal on the
power supply terminal block BAT. Ensure that the power supply
screw is appropriately tightened to secure the wire.
4. Place the battery back-up in the battery location as shown
in figure 15, ensuring that the orientation is as shown, the
positive terminal being the lowest.
5. Attach the battery brackets as indicated in figure 15 by hooking
one end of the brackets under the anchoring slots on the side
of the enclosure and the other end over the threaded posts.
6. Install, in sequence, the flat washers, split washers, and nuts,
tightening as needed.
7. Connect the wires from the power supply (B) to the battery (K)
ensuring that the red wire connects to the ‘+’ terminal and the
black wire connects to the ‘-‘ terminal.
8. Reconnect the power adaptor or turn on the main AC power to
the 660G XT.
NOTE:
For preventative maintenance, the battery back-up should be
replaced every 2 to 3 years, and tested every 6 months by
removing the main AC power.
5.6 Power Failure
In the event of an electrical failure, the system will revert to battery
back-up status for a period of 4 hours. If the electrical power is
restored within 3 days the system will recover automatically and
should require no additional programming.
When electrical power is restored after a power failure verify the
status of the LED D41 on the controller board (C). Refer to Annex
A, Table 3 for Status LED definitions. If the LED is OFF reprogram
controller board (C).
NOTE:
When the voltage of the battery back-up is too low the
controller board stops working and the relay on the controller
board (C) will return to its normal state. The peripheral
connected to the relay will then be either in a normally open
(NO) or normally closed (NC) state dependent on the wiring of
the device to the controller board (C).
5.7 Loading Recommendations
CAUTION: Do not exceed the load limitations
of the control panel.
!
The maximum recommended load for all output relays in the card
reader control panel is 1 Amp at 30 VDC. The tamper switch rating
is 1 Amp at 30 VDC.
The current supplied by the controller board (C) for the locking device
used is 0.75 Amps from connector J18, pin 1. Refer to Annex A,
Table 1.
5.8 System Deactivation
In order to deactivate the card reader control panel, disconnect both
terminals from the battery back-up, then disconnect the AC power
either by removing the power adaptor from the wall outlet, or by
shutting off the main breaker switch for the AC line to the wall outlet
the control panel is connected to.
