TE Technology TC-720 - Manual (Page 24)

1.5 Connect other applicable devices to the controller:
a) Connect optional external alarm LED indicators to JP2-10 (ALARM2) and/or JP2-8 (ALARM1), assuming ALARM1
will not be configured for PWM fan control.
b) Connect optional enable/disable switch between JP2-6 and JP2-7 (or other circuit ground location). The
controller will need to be software programmed to enable this feature (described in Section 4). Once
programmed, when the switch is closed (electrically shorted), the controller’s power output will be enabled. If
the switch is open, the output will be disabled. The switch could, for example, be a simple rocker switch or it
could be a thermostat. The current between JP2-6 and JP2-7 will be 2 mA when the switch is closed. Use a
switch with the appropriate contact ratings, such as gold plated contacts.
Connections, Other Applicable Devices
c) If you intend to use the controller to speed-control a fan rated for PWM control, connect the PWM speed-
control wire as shown below through the rubber face plate, and connect to JP2-8. Be sure to consult the fan
manufacturer for further details on the appropriate PWM frequency to use with the fan, minimum duty cycle
required for the fan blade to spin, etc.
