Figure 2

How to Open the

Series 920.

Before going further, open the Series

920

and pull the control chassis from its

case. Here’s how:

The control chassis fastens to the case with a single screw located on the

lower front panel. See Figure

Turn the screw counterclockwise to loosen it.

Three or four strip connector

plugs, in the rear of

the control chassis, feed

power and signals through the back of the casing to the triple terminal strip.

These plugs will let go as you pull.

When removing the Series

920

control from its case, pull firmly but gently.

When returning the control to the case, be sure you have the top up to match

the plugs with the case. The 920 will not fit in to the case upside down. Al-

ways check to see that it is oriented correctly.

Press the unit in firmly, then turn

the front panel screw clockwise to secure it.

How to Set the DIP Switches

The Watlow Series 920 has a Dual In-line Package (DIP) switch inside the

control on circuit board

appear in Figure 3. The switches are clearly numbered from left to right. You
