5. Refer to Figure 8, Page 10. Set the input volt-
age selector switch SW1 for the AC input
being used.
6. Refer to Figure 8, Page 10. Set switches
SW2 and SW4 in accordance with either of
the following:
• If local torque adjust potentiometers are
used, set to “up” position.
• If external or remote torque adjust poten-
tiometers are wired to the control, set to
“down” position. Refer to Figure 9 below.
Input/Output signal Relationships, when
makingthe settings required in steps 7 -
10. Circuit logic is diagrammed here for
your convenience.
7. Proper operating mode setting (switch SW3)
depends on how the control inputs are wired:
• Set SW3 in the “up” position for level
input operation from a single switching
device. Channel 2 input controls output
switching when the control is operated in
this mode.
• Set switch SW3 in the “down” position for
pulse input mode operation. This requires
input switching on both Channel 1 and
Channel 2 inputs.
8. Overexcitation Set-up
Switch SW5 controls the overexcitation pulse
to Channel 1 while switch SW6 controls the
overexcitation to Channel 2. to enable the
OEX, set the switch in the “down” position for
the channel to be overexcited. The “up”
positions disable the OEX pulses.

Notes:
1. Channel 1 input signal can be configured by
SW10 to provide same function with inverted
signal.
2. Auxiliary input shown configured as a Channel 1
input, can be configured by SW11 to provide
same operation as a Channel 2 input.
3. Diagram reflects current flow through optically-
isolated control inputs in either sourcing or
sinking made.
4. See set-up switches on back cover.
Notes:
1. Auxiliary input shown configures as a Channel 2
input. Auxiliary input non-functional if configured
as a Channel 1 input when control is configured
for a singal input from Channel 2.
2. Diagram reflects current flow through optically-
isolated control inputs in either sourcing or
sinking mode.
