Interlock
Connections
A terminal strip provides connection to the transmitter’s internal
safety interlock circuitry. An active interlock state occurs as a result
of either high coolant temperature or no coolant flow. It will also be
active for about 2 seconds after power up.
Interlock connections are made to the terminal strip on the front of
the unit.
1. Use number 22 AWG (or heavier) wire for interlock connections.
Attach solderless ring terminals to the wire ends to ensure safe
operation, and to ease installation.
2. Connect the interlock wires to the interlock terminal strip as
required for the transmitter in use.
AC Line
Attachment
Before applying ac power to the unit, make sure:
y Coolant is in the system.
y
Coolant is filled to the correct level.
y
The green wire at the supply end is fastened to ground.
The ac power supply may be either 115 or 230 V depending on the
unit requirements. AC line power is supplied to the 3-wire ac panel
module socket by means of the 10 foot cable and matching socket that
is furnished with the equipment. The third wire in the cable, coded
green, is the ground. For proper protection, if a 3-wire type plug and
outlet is not used, fasten the green wire at the supply end to a
satisfactory ground.
CAUTION
Before any RF operation of the load is attempted, the transmitter
interlock and ac line attachment to the equipment must be made.
First attach the transmitter interlock connec tions to the two
binding posts on the front panel and then connect the power cable.
CAUTION
The 115 V or 230 Vac line may be connected, but the ac power must
not be turned on unless coolant is in the system and filled to the
correct level. Damage to the pump will result otherwise.
