1. The Feed Reed Switch is a safety that will not allow the machine to operate if the feed cylinder is not fully

retracted. The Feed Reed Switch is located on the Feed Cylinder. To check that the Feed Reed Switch is

positioned properly, loosen the set screws and put an Ohm meter on terminals 7 and 9 in the trolley. Slide

the Feed Reed Switch back and forth until continuity is indicated, then tighten the set screws.

2. Check that the Air Regulator is set for 80 psi. Mounted on the top of the Trolley are two Adjustable Ex-

haust Mufflers. The front one adjust the speed of the Dwell Cylinder moving down and the rear one adjust

the speed up. These mufflers can become restricted or loose. If machine is sluggish or starts slamming

down, adjust these mufflers accordingly.

3. The First Pulse Reed Switch is located in the middle of the Dwell cylinder.

4. To check that the Dwell Reed Switch is positioned properly, loosen the set screws and put an Ohm meter

on terminals 6 and 11. Slide the Dwell Reed Switch up and down until continuity is indicated, then tighten

the set screws.

5. Mounted on the Feed Cylinder is a Feed Speed Control. The Feed Speed Control adjusts how fast the Pusher

with Pawl moves in and out. If adjusted too fast the pins may be tossed past the tip, if adjusted too slow

the pins will not be placed on the tip.

ACTION

PROBLEM

(A) Vibrator

(A) Check the Vibrator Circuit Breaker (Located on the rear of the Control Console.)

Circuit Breaker .

(208-230VAC approx.) If Circuit Breaker reads 208-230V, Circuit Breaker is

open. If so, push in Circuit Breaker to reset. If 0V, go to Step B.

(B) Vibrator

(B) Check the Vibrator Power Switch in the Control Console. (208-230V AC approx.)

Power Switch.

Between Switch Term 4B-2A, than 3B-1A.

Sensor and

Control Relay. Check the Track Sensor for the red LED. If the LED is not on,

Receiver

check the terminals G and H on the Receiver Board in the Control Console (top

Board

rear) for the 12 V dc. If the voltage is present, replace the Track Sensor. If the

voltage is not present at G and H, check for 24 V ac at terminals A and B. If

the voltage is present at A and B, replace Receiver Board. If the LED is on,

jump C and D on the Receiver Board. This should make the vibrator run. If the

vibrator runs, check the line of sight through Track Casting. If the line of sight

is good, replace the Track Sensor. If the vibrator still does not run, jump A and

F on the Receiver Board. If the vibrator now runs, replace Receiver Board. If

the vibrator still does not run, proceed to next step.

(D) Vibrator

To check the Vibrator Control Relay, test the voltage (24VAC approx.) at termi-

Control

nals #T2 and #T5 on the Vibrator Control Relay Board located in the Triangle

Relay.

Enclosure. There should be 24VAC at terminals #T2 and #T5 when there is no

(Relay-3)

weld pin at the Vibrator Sensor. If this voltage reading is correct, now check

the voltage (208-230VAC approx.) at terminals #T1 and #T11 on the relay

board. When the main power is on, terminals #T1 and #T11 should always have

voltage. Now check the voltage (208-230VAC approx.) at terminals #T3 and

#T9. If there is no voltage at terminals #T3 and #T9 and the above is correct,

replace the Vibrator Control Relay.

(E) Vibrator

(E) In the Control Console, check for voltage (208-230VAC approx.) at terminals

Speed

#1 and #3 on the Vibrator Speed Control. If there is 208-230VAC at terminals

Control.

#1 and #3 replace the Vibrator Speed Control.

(F) Vibrator

(F) Measure the resistance at the plug (two outside pins) of the Vibrator Base.

Coil.

The resistance reading should be approximately 60 ohms. If this reading is not

correct replace the Vibrator Coil.

(A) Vibrator

(A) To test the Vibrator Speed Control place your hand on the Vibrator Bowl and

from slow to fast and back. If you feel no change in the intensity on the bowl

or see any change in the intensity on the Vibrator Sensor Indicator, replace

the Vibrator Speed Control located in the Control Console. If a change in the

intensity is present proceed to the next step.

(B) Vibrator

(B) Turn the power off and remove the Vibrator Bowl and inspect the springs and
