Wiring the Hold switch:
An optional Hold switch can be
used to allow the load to remain
energized after the hand switches
are released. This feature is
useful for applications that have
long machine cycles.
The Hold switch is normally open
and must not be closed until the operator can no longer reach into the point of
operation. Once the Hold switch is closed, it should remain closed for the rest
of the machine cycle. The Hold switch circuit does not become functional until
the machine cycle has begun.
The Hold switch is connected to terminals marked "HOLD". The terminal to the
right is also used by the Reset circuit. Do not remove the reset jumper wire
unless you are installing the optional Reset switch as described below.
Warning!
The Hold switch must be mounted on the machine so that it
cannot close until the point of operation is no longer
hazardous.
Wiring the Reset switch:
An optional switch can be used to reset the Start Bar when a machine cycle is
completed.
Remove the jumper wire from
the terminals marked "RESET"
prior to installing the wires
connected to the reset switch.
The left terminal also shared
with the optional Hold switch (if
installed).
The Reset switch is normally closed and will reset the control when it is
opened. This switch must be closed before a machine cycle can be started.
