For the connecting cable use a mating XLR style connector such as the NC3FXX
manufactured by Neutrik AG
The switch over contacts are rated at 24V AC or DC 2A maximum.
The relay is rated 24Vac or dc at 2A; to prevent injury or equipment damage,
do not connect to greater voltages or attempt to switch greater currents.
Voltages as low as 22Vac can be hazardous in locations where wetting of the
skin can occur. When making up cable to connect your equipment to the relay
connector, on the TX150/TXF200, make sure that the insulation system used is
adequate to provide protection against the voltages output by your equipment
for switching by the relay.
Always use the correct size cable with correct class of insulation for the voltage
being switched. If in doubt contact the technical support team at Grant.
5.1.6 Emptying the LTC4
The R unit tank should be emptied to a safe level prior to moving. A drain tap is included
on R2, R3, R4 & R5 units to allow convenient emptying. See section 5.2.3 for full details.
Allow the liquid temperature to fall below 50
˚C before emptying.
5.1.7 Setting up and switching on
Follow instructions in section 5.1.3 to attach the pump connector plate and insulated
hose. Before filling and switching on, attach the open end of the hose to the application,
taking care to note the inlet and outlet.
Ensure all hoses are connected securely. Liquid will begin pumping
immediately once LTC4 is switched on.
Add the appropriate working liquid to the bath to at least the minimum recommended fill
level such that the float level switch is fully raised.
The control unit is connected directly to the mains supply with the IEC cable supplied
with the unit (230V units only).
Connect the refridgeration unit directly to the mains using the IEC cable provided).
Switch on the LTC4 control unit using the power switch on the rear. The motor will start
immediately and the buzzer will sound while the unit starts up. Switch on the
refrigeration unit using the power switch on the front of the unit. The LTC4 will start to
control at the set temperature
