8.4.3.4 Test run

Test run shall be performed after Installation, wiring and other setting.

Refer to the Installation and operation manual of each central control system and check the detail.

1 Check connection condition of Air conditioners.

Check the model name and connected unit quantity by using remote control switch.

In the case that control equipment is used, perform connection check at the central control equipment.

2 Check transmission Alarm.

Perform RUN/STOP by the central control equipment or remote control switch.

Check to ensure that no transmission alarm such as 03.32.35.60.61 (60 and 61 are only with central control equip-

ment) occurs.

3 Check of Activation State Monitoring

Monitor activation state from the LED on control PCB.

Check to ensure that LED1 is not keeping ON due to continuous collision. The cause of continuous LED ON is as

follows. Incorrect Setting of Master or Slave H-LINK Relays, end terminal resistance, looped wiring, etc. Check to

ensure that setting and wiring are correctly performed.

Check to ensure that LED2, 3 and 4 are flicking. If not, check to ensure that transmission is performed by checking

LED on PCB in the other unit. In the case that the above LED on the H-LINK Relay does not flick despite sending

signal from the other unit. Check the wiring connection, end terminal resistance setting, type of wires and wiring

length. If the fuse in the transmitting circuit is melted due to incorrect wiring, use Fuse Recovery setting.
