MAINTENANCE:
The Model RC-1T5A is designed to require a minimum of maintenance under all ranges of service conditions. There
are no moving parts except the output contactor relays. With proper installation, no abuse or tampering, the unit should
deliver at least 10,000 hours of trouble-free operation.
5.1
MAINTENANCE CONCEPT:
The unit may be maintained readily by technician level personnel.
The printed circuit boards are not readily
repairable in the field. Return defective printed circuit boards to Control Industries for repair / replacement by
the manufacturer
. A stock of one each substitute cards should be retained to verify a suspected defective card by
simple substitution procedures. All other elements of the receiver-controller may readily be checked utilizing normal
electrical test procedures involving no special testing equipment other than a standard volt-ohmmeter. A standard
headset may be used to monitor the receiver at the audio jack.
5.2
OPERATING CHECKOUT:
The service technician may determine proper operation of the receiver-controller by completing the following
checklist:
(1) Check the presence of primary line voltage as measured between input terminals marked 115VAC and
neutral.
(2) Press AC power switch and observe Green DC power indicating LED inside the controller housing.
Illumination of this DC indicator implies proper power supply operation.
(3) Depress red test button five consecutive times within five seconds. This result is closure of Relay K-1 and
the illumination of the red LED indicator adjacent to relay K-1 on the Relay Card.
(4) After elapse of 5 seconds the timer indicator should extinguish.
(5) Depress white reset button and confirm all relays and light go out.
(6) Place a short across Remote Disable terminals. Verify light next to terminals lights. Verify that when test
button is pressed three, five, or seven times no relays close. Remove short.
(7) Place the Decoder Disable switch in the on position. Verify light next to switch lights. Press red test button
seven times within 5 Seconds. Wait for the timer light to go out. Press the red test button three, five and
seven times to verify that the output does not change. Wait 15 minutes for the timer to disable the relays.
Press red test button three, five, or seven times to verify ability to reactivate after timeout.
The above procedures accomplish a complete operating check of all elements and functions of the Receiver-
Controller RC-1T2A.
