PROBLEM

The DLM-4 Zone Controller is

connected to power, but it

does not seem to be working

/ no display

After setting up the DLM-4

Zone Controller, the fixtures

are still not being turn on or

controlled.

The Zone does not seem

to be controlled by the

temperature sensor correctly.

The temperature display

within one or more zones

does not seem to be correct,

unit, and now the lights will

not turn on.

RESOLUTION

Check the low-volt power

supply is plugged in properly

to the DLM-4 Zone Controller.

Each ballast must be manually

switched to External (DLM-4

Zone Controller) control. Verify

the selector switches on the

ballast are correct.

Within each Zone settings,

you can select which

temperature sensor you want

to "assign" to that zone. Verify

the Sensor setting is correct.

Make sure the temperature

sensor is not receiving direct

HID light which would increase

the temperature reading.

There is a 15-minute time delay

after a power failure to prevent

the lamps from hot-starts.

The 315 watt fixtures cannot be

dimmed. However, they can be

turned OFF if the temperature

reaches the "Off At" setpoint.
