Control Wiring (continued)
Bulletin 160 Analog Signal Follower models (catalog # 160X–XAXXNSFlXX) can be operated using
either a unipolar (frequency control only) or bipolar (frequency and direction control) analog input. Use
Parameter 46 – [Input Mode] to select the control method for start, stop, and direction control. There are
four settings from which to choose (shown in Table 2.E below). For all settings, the controller will reverse
when the voltage on the analog input transitions from positive to negative. In two-wire control (Parameter
46 – settings 1 and 3), negative voltage on the analog input will start the controller, which may be
unintended. This applies to both a negative offset in the analog command, or noise which causes the
analog input to go negative. Refer to Table 2.E below for the recommended installation instructions for
all Parameter 46 settings.
ATTENTION: Read the
following sections carefully before
installing the Bulletin 160 SSC.

ATTENTION: When changing the parameter setting for P46 – [Input Mode],
you must cycle power for the change to take effect.
ATTENTION: The program keypad module stop key simulates momentary pushbutton
operation. For “two wire” control schemes (P46 – [Input Mode], setting “1”) the
program keypad module stop button will only provide a “stop” function while the stop
key is depressed.
