SYMPTOM:

Hi Again

It took Murray over ½ hr extra to load his truck. The problem is the key pad on the load arm side of the plant.

He spent the half hour hitting the key until it finally would accept. This problem has been progressing for a few years. We were are a sliver away from total failure. I believe this needs immediate attention. ( A new key pad.)

I will phone PT and let them know.

Thanks

Tim


TESTING:

Just so we are correctly identifying the problem we should do the built in Multiload keyboard test

 

The Multiload must be in program mode (bolt removed)

7 zeros  then next

Select diagnostics, enter

Keypad test, enter

 

Then every key you hit (except EXIT which gets you out of test mode) will ECHO back on the screen

Go for the problem keys, enter multiple times at a normal speed

Be sure to count and match presses with what appears on the screen

When done, press EXIT

EXIT all the way out and replace the program key

….done



REPLACEMENT: Authorised personnel only, Hot work permit may be required

Call PT for replacement Keyboard

Keypad went out last night. , Purolator tracking will be forthcoming

Tim please keep this in mind if you know the Purolator person or drop time/location


POWER DOWN THE UNIT

CRASH the yard, should take the Multiloads down

 OR

 Disconnect power terminal block from board (lower right side of board inside ML)

Green three position connector

Wear insulated gloves, terminal power live

 

To replace the keypad, open the front door

Remove the cable from the back of the keypad, locking tab

See the multiple screws that hold the keypad plate in place

ALSO the heater has a LONG screw that goes through the plate and must be removed first

 

Remove the keypad with light pressure. Old adhesive seal may be holding it in place

Remove the remnants of the adhesive outside seal from the access hole (new keypad has adhesive attached)

Remove the adhesive backing paper from the NEW keypad, precisely locate

Unpack the rubber ineer metal plae seal. Install associated with the retaining screws

Install the backplate with screws. Reinstall the heater, terminate the plug into the back of the keypad

Close up and repower unit

 

You may go through the kEYPAD test process if you like to verify operation


Hi Tony

Thought about CRASHING the yard but figured that would disturb a lot of suppers.

Unplugging the three pin terminal worked fine.

Board is changed and tested fine.

PS….. do you think the drivers would notice if I installed the board upside-down? LOL.
