Electronic Speedpot Interlock
The -1 adder board connects to the 125 series board through use of a female connector and plastic standoff support.
When incoming AC power to the control is applied, the Electronic Interlock will prevent the motor from starting until the speedpot
is first rotated to the zero position and then rotated clockwise toward the set speed.
Also, should the incoming AC power be interrupted for any reason, then restored, the Electronic Interlock will prevent an automatic
restart of the motor. To restart, the speedpot must first be rotated to the zero position and then rotated clockwise toward the set
speed.
CAUTION: The Electronic Interlock becomes inoperative if SCR failure should occur.
-2A option
Individually Adjustable Linear Accel and Decel
This option plugs into the five position expansion connector
on the 125D main board. The -2A option overrides the fixed
accel ramp built into the 125D control, providing indepen-
dently adjustable linear accel and decel from 0.5 to 8.0
seconds. To install, flip over the -2A option board so the
printed circuit lines are visible. Align the male connector CN1
(-2A option) with the female connector P2 (125D board) so
terminal CN1-1 fits into P2-6, CN1-2 in P2-5, etc. Align the
plastic stand-off on the -2A option board with the hole shown
on the 125D main board. Once connectors and stand-off are
aligned, snap into place. Adjustment of both trimpots is
accomplished via the labeled access holes on the back side
of the -2A option board. Full CCW rotation equals minimum
accel or decel time and full CW rotation equals maximum
accel or decel time. Note: Each trimpot operates indepen-
dently of the other.
