Equipment Maintenance Part 2

Mar 13 2014

It is important to carry out regular maintenance checks on your equipment to ensure you avoid any malfunctions or failures. In the event of a malfunction it is necessary to check if the TriScan 50 Motor is functioning correctly.

Follow our guide on the TriScan 50 Motor, one of a series of Equipment Maintenance posts.

Equipment Maintenance Part 2–Checking the TriScan 50 Motor

The following tools will be required:

IMPORTANT : THIS PROCEDURE MUST BE CARRIED OUT BY A QUALIFIED TECHNICIAN WITH SUITABLE TRAINING, AS DANGEROUSLY HIGH VOLTAGES ARE PRESENT

  • Slotted, Cross and Posidrive screwdrivers
  • TORX –T10 Screwdriver
  • 19mm Spanner
  • 10mm Allen key

Ensure that the TriScan 50 Motor is powered down.

Unscrew the two securing nuts by hand and remove the washers on each of the Strain Rods, then the lift off the Cross Beam as shown below.

Remove the four screws in each of the washers sealing the Strain Rods to the Base Cover with a Cross head screwdriver and slide up the rubber seal and washer.

Unscrew both Strain Rods and Remove (note that this may require use of the 10mm Allen key and 19mm spanner for the securing nut and bolt at the top of the Strain Rods if tight

Remove all screws from the Front Panel using a Posidrive screwdriver and carefully lift away (there will be four connectors to the Front Panel).

Unplug the four connectors attaching the Front Panel to the PCB and remove.

Loosen the securing screw on the bellow clamp with a slotted screwdriver and unscrew and remove the Platen (using the Allen key as a lever if tight) and then lift off the bellow clamp.

Unscrew all the bolts securing the Base Cover (including the one under the warning label which needs to be peeled off) using a Posidrive screwdriver.

Lift the Base Cover up enough to be able to unplug the Earth push-fit connection and enable complete removal of the Base Cover.

Remove the TriScan 50 Motor cover by unscrewing the four bolts (note that a special screwdriver (TORX –T10) is needed to remove motor cover), leaving Earth wire attached to cover. Reattach the four connectors to the PCB that were removed earlier and place the Front Panel where the display can be seen.

SWITCH THE POWER BACK ON AND ENSURE THAT NONE OF THE ELECTRONICS ARE TOUCHED UNTIL THE POWER IS SWITCHED OFF AS DANGEROUSLY HIGH VOLTAGES ARE PRESENT.

Wait until the TriScan 50 Motor has initialised (this can be seen on the Front Panel display). Observe the LED in the corner of the Motor as shown.

If the LED is blinking then the Motor has a problem and may need to be replaced. Contact VJ Tech for assistance.

If the LED Indicator is not illuminated, there is a Power Supply connection problem. Use a Multimeter to check the incoming power and isolate and then rectify the problem and continue.

If the LED is permanently illuminated, the system considers the Motor to be functioning correctly. Continue as follows.

POWER DOWN THE TriScan 50.

While the TriScan 50 is in this state, set the ‘Block Detection’ dip switch to OFF. This may help to alleviate intermittent Platen Mechanism problems. The ‘Block Detection’ dip switch is setting number 4 as indicated below.

Using the end of a small slotted screwdriver, ensure that the dip switch is set to the right (OFF).

SWITCH THE POWER BACK ON AND ENSURE THAT NONE OF THE ELECTRONICS ARE TOUCHED UNTIL THE POWER IS SWITCHED OFF AS DANGEROUSLY HIGH VOLTAGES ARE PRESENT.

Check that the LED Indicator in the Motor is permanently illuminated.

Using the Front Panel buttons, check that the Platen Mechanism moves up and down freely. If the Platen Mechanism does not move, contact VJ Tech – a replacement motor will be needed.

Power down the TriScan 50.

Reassemble the TriScan 50 Motor in the reverse order, remembering to connect the Earth Push-fit before reattaching the Base Cover.
