The fail-safe and external interlocks are active and may be on or off. External site
system wiring must be connected to these interlock terminals or jumpers must be added
at the terminals to turn these indicators off before the transmitter can be turned on. The

STEP 1: Check the external interlock by operating whatever is connected to external
interlock, if there is nothing to connect place jumper at TB1-1 and 2 on I/O panel.
STEP 2: Press transmitter ON push-button.
STEP 3: Check for the external blowers (supply and exhaust blowers) to start.

transmitter should shut off. Press ON button. The transmitter should not come on. Re-close
the circuit. The external interlock status indication should go out. The transmitter should
come back on if the setup selection is "auto-restart". If setup option is "lockout,” the
transmitter should not come back on until a manual ON command is given.
STEP 6: Check operation of RAISE and LOWER buttons, both on the control panel of the
cabinet and the GUI screen.
STEP 7: If the system has a remote control, place transmitter in the REMOTE mode and
check for operation of transmitter ON/OFF and RAISE/LOWER from the remote.
