Notes:
1.
If the available analog speed reference signal voltage is not isolated, an optional Signal
Isolator Board, model BC145, may be installed. Reference: paragraph 4.8, page 21 for
Signal Isolator Connection information.
2. When using an external analog signal, the main speed potentiometer must be
disconnected from terminals P1, P2, and P3. The MIN trim pot may need to be adjusted to
achieve 0 output voltage.
Note: The Start/Stop function may be bypassed by connecting a jumper wire across the
"Start" and "Com" terminals.
4.7.3 Remote Start/Stop Switch - A remote
Start/Stop
Switch may be installed by
disconnecting the wires from the "Start",
"Com", and "Stop" terminals, and reconnecting
the terminals to a remotely mounted switch.
See Figure 9.
