Valley Classic Control Panel
21
Overview
Start-Stop / Safety Override Switch
The control panel is equipped with a combination
Start-Stop Safety Override rocker switch. See Figure
21-1.
To start the machine, press and hold the switch in
the START position for approximately three seconds
and then released at which time the switch will return
to the center neutral RUN position. See Figure 21-1.
If the machine safety circuit is complete, the safety
return light will remain lit and the machine will con-
tinue to run. See Figure 21-1.
To stop the machine, move the rocker switch to the
STOP position. See Figure 21-1.
If the machine safety circuit is broken (open) due to
span misalignment, it will be necessary to override
the safety circuit momentarily to realign the machine.
However, the machine must be in full view of the op-
erator, if the machine is not in full view of the opera-
tor, DO NOT override the safety circuit.
When the Start-Stop switch is held in the START
position, the machine safety circuit is bypassed and
the machine will run until the switch is released. The
switch should never be held in the START position
for more than three seconds at any one time.
To override the machine safety circuit, press and
hold the switch in the START position for no more
than three seconds at any one time. See Figure 21-1.
Inspect the entire machine after each safety override
attempt.
