KT-100 Controller Maintenance
To ensure the best operating conditions, it is highly
recommended to test the KT-100 controller by performing the
following tests.
Bi-annual test for battery
This test will ensure that if a power failure occurs, the battery
will be able to support normal operations. This test should be
performed twice a year.
1.
Remove AC power from the power supply and power
the controller using the battery for one hour.
2.
Once the test has been performed successfully,
reconnect the AC power to the power supply. No low
power or power failure events should be reported to the
system workstation.
Annual test for emergency lithium battery
Measure voltage of lithium battery when power is totally
removed from the controller (AC & DC power). To ensure
maximum operation and prevent loss of power, if the lithium
battery voltage measures below 2.5 VDC, please contact your
distributor to return the KT-100 for maintenance.
Mounting the KT-PC4204
The KT-PC4204 package should include the following items:
◗
One KT-PC4204 circuit board,
◗
One ground wire assembly,
◗
Five plastic standoffs,
◗
One 5 A replacement fuse.
The KT-PC4204 should be located inside a compatible cabinet
(Kantech part no. KT-4051CAB), mounted on a dry, secure
location. Preferably, it should be placed at a convenient distance
from the connected devices.
To mount and connect the power supply:
1.
Press the five plastic stands offs through the mounting
holes at back of the cabinet.
2.
Secure the cabinet to the wall in the desired location.
Use appropriate wall anchors when securing the cabinet
to dry wall, plaster, concrete, brick or other surfaces.
3.
Press the circuit board into the plastic stands offs to
secure the module to the cabinet.
4.
Mount the power supply unit.
5.
Install 120 / 230VAC / 16VAC, 40VA, class 2 wire-in or
plug-in transformer.
6.
Place battery in the cabinet. If the AC supply is removed
form the PC4204, the backup 12volt battery (if fully
charged) will support normal operation for up to 12
hours. An internal battery verification will cut the output
power if the battery voltage level falls below 9.5 V DC.
7.
Connect the AWG#18 grounding wire to EGND
NOTE:
Since the KT-100 uses high performance communica-
tions, proper grounding must be provided to ensure proper oper-
ation. An AWG#18 single conductor solid copper wire must be
used to ground each KT-PC4204 power supply to a good earth
ground as per the local electrical code (be careful of ground
loops). The ground clamp should be located below any other
ground.
