Step 1 Ċ Make the same assumption as in Paragraph

6.5.1, Step 2.
Step 2 Ċ Connect the black pigĆtail jumper on the InterĆ

face Module to the 50 mA pin. (Refer to Figure 6.10.)
Step 3 Ċ Locate the Auto Minimum Speed potentiomeĆ

ter on the Interface Module. Turn it CW to the third dot

which represents aoneĆthird turn.
Step 4 Ċ Place the controller in the AUTO mode, if so

equipped Locate the Auto Maximum Speed potentiomeĆ

ter. Adjust it to obtain the desired preset speed. (CW inĆ

creases speed, CCW decreases it.)
6.6 Field Supply Ċ The Field Supply Kit provides fullĆ

wave field excitation for shuntĆwound dĆc motors. (Refer

to Figure 6.11.) It may be optionally applied to controllers

from 1/4 thru 1Ć1/2 hp. (It is a standard feature for 2, 3 and

5 hp Regenerative MinPak Plus controllers.)
DĆC field supply voltage and maximum field amperes are

listed in Table 2.D.
The Kit is an assembly consisting of a terminal block, a

Field Supply Power Cube, two wire harnesses, and a

Mounting Bracket. The user provides the F1/F2 conducĆ

tors to the drive motor. No other equipment is required.

Figure 6.11 - Field Supply Kit

To install the Kit, follow these procedures.
Step 1 Ċ Mount the assembly bracket to the top of the

circuit breaker bracket with the screws securing the cirĆ

cuit breaker.
Step 2 Ċ Wire from the Field Supply Power Cube to terĆ

minals 51 and 52 on 2TB by passing the wires under the

circuit breaker bracket.
Step 3 Ċ If Paragraph 3.5.2 was followed, the user supĆ

plied field wiring conductors should be drawn into the

Chassis. Route them as indicated in Figure 3.7. Move

them to the screws on 3TB and connect F1/F2 according

to the la bel or Figure 6.12.

6.7 Auxiliary M Contacts Ċ With the optiona l Auxilia ry

M Contact Kit, the ON/OFF status of the Regenerative

MinPak Plus is able to be interlocked with userĆsupplied

devices. (Refer to Figure 6.13.) Typical applications inĆ

clude pilot/indicator lights, alarms, and interlocking with

other control circuits dependent on the drive system.

Figure 6.13 - Auxiliary M Contactor Kit

The Kit provides asingle pair of Form C contacts, one

normally open (NO) and one normally closed (NC). Both

share a common terminal. (Refer to Figure 6.14) These

contacts function when the M contactor is energized.

The Kit contains only a Module that has a wire harness

attached.
