Supervisor Key Switch
The supervisor key switch (rate lockout) is located on
the spray control enclosure faceplate (Fig. 6). When the
supervisor key switch is in the OFF (locked) position, the
application rate switch is disabled.
The supervisor key switch used on sprayers with serial
numbers below 270000000 is shown in Figure 7. The
key switch used on sprayers with serial numbers above
270000000 is shown in Figure 8.
Testing
1. Remove spray control enclosure faceplate, locate
supervisor key switch and remove wire harness connec-
tors from switch.
2. Test switch for continuity as follows:
A. For sprayers with serial numbers below
270000000 (Fig. 7), when the key is in the ON posi-
tion, continuity should exist between the two switch
terminals. In the OFF position, there should be no
continuity between the switch terminals.
B. For sprayers with serial numbers above
270000000 (Fig. 8), when the key is in the ON posi-
tion, continuity should exist between switch termi-
nals A and D. In the OFF position, there should be no
continuity between switch terminals A and D. Switch
terminals B and C are not used on the Workman 200
sprayer.
3. Reconnect the harness connectors to the switch af-
ter testing. Install console panel to machine.
