TABLE 5.A - TROUBLESHOOTING SUGGESTIONS FOR THE

THREE PHASE MINPAK PLUS CONTROLLER (Continued)

Symptom

Probable Cause

Recommended Procedures

4. In nonĆreversing

controllers

only

. .

Controller's M

contactor not

picking up when

START switch is

pressed (closed).

Faulty M contactor

Open the power disconnect switch.

Examine M contactor for firm seating.

On the M contactor, connect an ohmmeter on 139 and 39 wires.

The reading should be 150 to 1000 ohms.

If these readings cannot be obtained, replace the M contactor. (Refer to Table 6.A.)

pressed (closed).

Faulty START/

STOP Switch

Check START/STOP switch, but first remove aĆc line power at main disconnect

Connect ohmmeter to pin 32 for Local Operators station or terminal 32 on the remote

operator adapter.

Place switch in START position. If functioning correctly a short will be indicated on the

meter.

Place RUN/JOG in RUN position connect ohmmeter to terminals or pins 32 & 35

respectively.

Place switch in STOP position, which should open if functioning correctly.

5. In reversing conĆ

trollers

only

. . .

Controller's M

contactor not

picking up when

FORWARD/REVERSE

switch malfunction.

Examine Remote or Local Operator on Regulator Module for firm seating and proper

wiring and pin connections.

Test FORWARD/REVERSE switch. Use basic technique outlined above for the

START/STOP switch.

picking up when

Start switch is

pressed (closed).

M contactor

malfunctioning.

On the Auxiliary M pins located on the Regulator Module, connect an ohmmeter.

Place it on the pin 39 and pin 67.

Place the FORWARD/REVERSE switch in the FORWARD position. The reading should

be approximately 150 to 1000 ohms if it is operating properly.

Without changing test points, place the switch in the REVERSE position. The reading

should be about 150 to 1000 ohms if it is operating properly. If a short is observed,

remove jumper J9 and repeat the test.

If a 150 to 1000 ohms resistance reading cannot be obtained when the switches are

open, the M contactor is malfunctioning and must be replaced.

6. M contactor picks

up but remains in

only when START

RUN/JOG switch is in

JOG position.

Place the RUN/JOG switch in the RUN position.

only when START

pushbutton is

pressed and held

in.

CR relay not picking

up.

Connect a voltĆohmmeter on the Remote Operator Adapter if used. Place it on

terminal 35 for both remote & local control.

Connect the second probe to connection 139 connected to the MinPak Plus M

contactor.

The reading should be +24 VDC for normal operation.

Next, shift the probe from terminal 35 to terminal 38 on the same terminal board.

However, leave the second probe where it is.

Press the START switch, The reading should be approximately 24 VDC for normal

operation.

Press the START/STOP switch to STOP, and then START. A 24 VDC (approximately)

reading should continue to appear. If it does not, the CR relay is not picking up. In this

case, replace the Regulator Module.

7. Drive motor does

not run, but M

contactor and CR

pull up.

(Use this proceĆ

dure only if conĆ

troller does

not

have optional Test

Meter Adapter

Kit.)

No input signal from

SPEED potentiometer

on Control Station.

If the controller does not have an optional AUTO/MANUAL switch, inspect the

Regulator Module to determine that jumper J4 i

s In place

. (The jumper is removed

when the AUTO/ MANUAL switch is installed.)

Check the SPEED potentiometer on the Control Station. First, open the power

disconnect switch.

Connect a voltĆohmmeter to the Regulator Module Remote Operator Adapter inputs, if

used.

Connect one lead to terminal 28. Connect the other to terminal 20. (Refer to Figure

3.4 for a Remote Station,)

For proper operation, the reading should be 5K ohms,

Disconnect the VOM lead from terminal 20. Connect it to terminal 426.

Turn the SPEED potentiometer from 10 to 0. The resistance should vary from 5K to 0

ohms. If it does not, replace the potentiometer.
