10. Troubleshooting
Warning!
WARNING! Electric Shock Hazard. These tests must only be run by a
Qualified Technician.
10.1. Curtain machine does not operate Manually.
1. Make sure that the PVR-H is getting voltage. Put meter leads across the AC input labeled BLACK
and WHITE. This should read 110vac or 240VAC depending on model.
2. Check fuse at PVR-H. Fuse should be a 10 Amp.
3. Check curtain machine and make sure that the cam block is not on the limit switches.
4. Check fuse on the circuit board inside the panel (F1) and make sure that you are reading 12VDC on
both sides of this fuse. Fuse should be a 2 amp mini fuse. Note the black lead of your volt meter
should be on the terminal labeled SENSOR,BLACK\SHEILD whenever measuring DC voltages.
5. Checking at the Sys500 board on the Primary Unit the RED should always have 12 volts DC. If you
read 12VDC at this terminal, check the terminal labeled WHITE. When the manual switch is off you
should have 12VDC. When the manual switch is in the 'open' or 'close' position, you should read less
then 2.5VDC. Now check the terminal labeled BLACK. When the manual switch is in open you
should have 12VDC on the terminal labeled BLACK. When the switch is in the closed position you
should have less then 2.5VDC. The secondary unit will not operate in the manual position.
6. If voltages are not correct you need to check and make sure that the 3 conductor cable that connects
from controller to PVR-H does not have a short. Disconnect power from the ICS-500 and PVR-H.
Then disconnect 3 conductor cable from the PVR-H and ICS500 making sure that they are not
touching each other and then measure for a short.
7. Disconnect power from PVR-H and remove 8 conductor cable and check the POWER TRAK unit.
Refer to the POWER TRAK manual for trouble shooting.
10.2. Curtain machine does not operate Automatically
8. Check to see if the unit will operate manually, if not repeat steps 1-7.
9. Check your program settings to make sure they are correct.
10. Check to make sure that your sensor readings are correct.
10.3. Temperature Sensors not reading correctly
11. If the temperature sensor reads -19.9 degrees, the cable is broken or disconnected from controller.
12. If temperature sensor is reading 130 degrees then the cable or sensor is shorted.
13. Check the sensor with an ohm meter. Remove sensor from controller and measure resistance across
the sensor. Refer to the resistance chart.
14. If sensor is only off 1 to 5 degrees then it probably needs calibrating.
15. If sensor is erratic you need to disconnect sensor cable and replace it with a sensor with short leads at
the controller. If the sensor is still erratic the problem is in the Sys500 board.
10.4. A Stage not working correctly
16. Check and make sure that the controller is calling for stages to be on by observing the display.
17. Make sure that the switch on the contactor panel is not in the off position.
18. Make sure that the stages power is on in the breaker panel.
