Dove Systems DM 624 RM - Manual (Page 4)

When the Dimmermaster is connected to its power source by a flexible rubber cable, the ground connection is made
through a wire in the cable. For maximum safety and to comply with electrical codes, this connection must be made.
Cables supplied by Dove Systems are pre-wired for this connection and include the necessary green wire. Be sure
this is firmly bonded to a ground connection box, a cold water pipe, or a known earth ground.
When the Dimmermaster is connected to its power source by conduit, the ground connection can be made via the
conduit itself. If flexible conduit is used, a separate bonding conductor will usually be required. Always check your local
codes for hook-up before operating this equipment. It is recommended that power connections to the Dimmermaster
be made by a qualified electrician.
E) LOAD CONNECTIONS
The dimmer pack consists of six dimming channels. The Dimmermaster will dim any load from 1 watt through 2400
watts at 120 volts. The load may be incandescent, inductive, or resistive. This includes conventional incandescent,
quartz incandescent, rain-lights, pin beams, and similar lamp loads. This does not include fluorescent or neon lamps.
Dove Systems offers a solid state transformer to dim other types of loads, such as 12 volt MR16 lamps.
The output connectors can be U-ground receptacles, stage pin receptacles, twist-lock receptacles (L5-20R), or a
terminal block. If your unit has receptacles installed, merely plug the load into the outlet which corresponds to the circuit
you desire to use. For terminal-block-only units, there is one lug for each output and a neutral bar for all neutrals. Lugs
are numbered according to their circuits. There should be a separate neutral returning from each load circuit.
F) CONTROL CONNECTIONS AND OVERTEMPERATURE SENSING
The Dimmermaster 624 can take either of two control protocols: USITT DMX-512 or 0 to +10VDC analog. DMX
control input connections are made through the five pin male XLR on the front of the unit. Analog 0 to +10VDC
control input connections are made through the DB15 male on the front of the unit.

Pin 5 of the XLR is the overtemp line. When the temperature of the heatsink exceeds 70 E Celsius, pin 5 is
pulled to signal common. Some controllers, including Dove Systems memory controllers, read this and display
an overtemp warning message.
When the temperature of the heatsink exceeds 75 E Celsius, the control is cut off. This prevents overheating. When
the heatsink cools, the loads begin to work again. If this happens, the air circulation around the dimmer should be
improved. Check that the internal fan has not failed.
