Thermolator TW Series UGH025-0504
3-18 INSTALLATION
TW-2 CONTROL
INSTALLING THE
AUTO START
FEATURE
If you have a TW-2 model, you can automatically start and
stop the Thermolator from a remote switching or timing
device that has power contacts rated 110VAC, such as the
process machine control.
Wiring the device to the Thermolator is accomplished through
a dry contact to the appropriate terminals on the motherboard.
After wiring the device to the unit, Auto Start must be
enabled by configuring a dip switch on the motherboard.
Disconnect and lockout power to the unit.
Open the electrical enclosure.
Punch a small hole in the left side of the
electrical enclosure. The hole must be large enough to
accommodate conduit for the power contact wires from
your switching or timing device.
Insert the two power leads from the device
through the conduit into the electrical enclosure.
Connect the 110VAC device contact wires to
the Auto Start terminals. Make sure terminals are
screwed tight.
