Problem Solving

CAUTION: If any part of the system is damaged, do not use it. Call your local GenRad Service Centre immediately for a substitute part. Refer to 'Parts Ordering'.

CAUTION: With the exception of those parts referred to in the Servicing and Maintenance section, there are no user serviceable parts. All servicing must be carried out by GenRad Service Centres.

PDU Self-Test

The system self test routine should be run periodically even if there are no apparent problems with the system. Running the system self-test will identify any problems before they impact on productivity.

If it is suspected that the system is operating incorrectly, run the PDU system self test option on the main menu).

If the system self test will not run, or the PDU will not switch on, the instructions in this section must be followed carefully.

If one of the following test steps advises you to order or fit a new part, make a note of the test step, part number and description. Then follow the parts ordering procedure later in this section.

1. Connect the mains power to the base station. Is the green base station indicator illuminated?
   YES - Go to step 4
   NO - Go to step 2
2. Check the mains supply, then check the mains lead. Is the mains lead faulty?
   YES - Renew the mains lead.
   NO - Go to step 3
3. Remove the electronic module from the base station.
   Using a small screwdriver, open the fuse drawer below the power socket on the rear of the module (Fig 16). Remove the fuse and fit the spare fuse. The fuse must be IEC 127 approved ceramic type 250V 2A (T). Re-install the module into the base station, power up the system. Is the base station green indicator illuminated?
   YES - The fuse was faulty
   NO - Renew the electronic module (0019)
