STEPCORRECTIVE ACTION

 

 

1

With the AC power model, make sure the power cord is properly connecting the IES-1000’s power

 

socket to an appropriate power outlet. Refer to the Hardware Specifications appendix to make sure

 

you are using the correct power source.

 

With the DC power model, make sure the power wires are properly connecting the IES-1000’s power

 

terminal to an appropriate power supply and the power supply is operating normally. Refer to the

 

Hardware Specifications appendix to make sure you are using the correct power supply.

2

Make sure the network module is properly installed in the IES-1000 (refer to the Hardware Installation

 

chapter).

 

 

3

With the AC power model, make sure the fuse is not burnt-out. Replace the fuse if it is burnt out (refer

 

to the Removing and Installing a Fuse appendix).

4

The LED itself or the unit may be faulty; contact your vendor.

 

 

8.2The ALM LED Is On

The ALM (alarm) lights when the IES-1000 is overheated and/or the fans are not working properly and/or voltage readings are outside the tolerance levels.

Table 8-2 ALM LED Troubleshooting

STEP

CORRECTIVE ACTION

1Make sure you can feel and/or hear the fans working - working fans emit a low buzz and blow air. If the fans are not working properly, make sure the power connector is connected properly.

Contact your vendor if the fans do not work. Do not remove fans from the IES-1000. Only a qualified distributor should remove or repair fans.
