Transport, Alarm Silence, and Temperature Override Switches
The transport, alarm silence, and temperature override
rocker switches are located on the control console (Fig.
18). These switches have common switching logic.
The switch terminals are marked as shown in Figure 19
and Figure 20. The circuitry of these switches is shown
in the chart below. With the use of a multimeter (ohms
setting), the switch functions may be tested to determine
whether continuity exists between the various terminals
for each position. Verify continuity between switch termi-
nals.
