Maintenance

4.1 Cleaning the Controller

With the enclosure securely closed, wipe the exterior with a damp cloth.

4.2

Fuse Replacement

The instrument contains two mains fuses. Failed fuses are an indication that an equipment problem could exist. Problem resolution and fuse replacement should be performed only by qualified service personnel. Refer to Figure 4-22and the following steps to replace the fuses:

1.Disconnect power to the controller (including power to relays if powered).

2.Open the hinged controller cover by completely loosening all four captive screws in the cover.

3.Remove the high voltage barrier; pull out on the lever of the captive fastener then pull straight out on the barrier. Set the barrier aside for reinstallation.

4.Remove the fuses and install new fuses of the same type and rating (T, 1.6 A, 250 V, slow blow).

5.Reinstall the high voltage barrier.

6.Close the controller cover and hand-tighten the four screws.

7.Reconnect power to the instrument.
