-1 option

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 auto-

matic 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 independently

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 independently of the other.
