Why do my Lehigh DX3 dimmers overheat and shut down?
If the red OT light on the individual dimmer comes on, it means the thermostat is sensing a temperature that is too high. Make sure that air movement is not obstructed and that the dimmer is not overloaded.
What to do if all Lehigh DX3 Control Systems dimmer circuits are full and cannot be dimmed?
If all dimmer circuits are at full intensity and cannot be dimmed, ensure that the Panic bypass switch on the backplane is in the “normal” position. Also, verify that the system is not in the “Fire Alarm” panic mode or that a Backup Cue is not active.
Why does the fan in my Lehigh DX3 run all the time?
The fan will run whenever there is a DMX link and/or if there is an architectural signal going to at least one of the dimmers in the rack.
How to fix no display on Lehigh DX3 Control Systems RCI?
If there is no display on the RCI, but the Lehigh Control Systems appears to work, it may be due to a power outage. Try turning the system off for 30 seconds and then rebooting it.
What to do if architectural controls don't control lights in Lehigh DX3 Control Systems?
If the architectural controls work but do not control any lights, try a system reboot, as the Dimmer Control Card may need to be re-initialized.
Why does my DMX console not control lights on Lehigh Control Systems?
If the architectural controls work, but the DMX console does not control the lights, check that the DMX indicator light is lit. If it's not, ensure your console is plugged in and transmitting DMX.
What to do if all control power is out on Lehigh DX3?
Check for AC power, and ensure that the phase 'A' fuse is not blown (F1 or F2).
What to check if one phase of dimmers does not work on Lehigh Control Systems?
If one phase of dimmers does not work, check that main power is applied, that one of the fuses on the backplane control card is not blown, and that the indicators on the Dimmer Control Card are all lit solid.
What to do if the fan does not come on in Lehigh Control Systems?
If dimmers come on but the fan does not, check for obstructions and ensure the blades spin freely. If voltage is present at the fan but it still does not turn, replace the fan.
How to troubleshoot one dimmer that does not work on Lehigh Control Systems?
Check that the LED indicator on the dimmer is lit. If it is, swap the dimmer with an identical unit to see if the problem tracks with the module or the circuit. Also, check that the lights are not burned out.
