The AUX 3 pushbutton can be designated as an
auxiliary motor select. As an example for
systems that have a main and auxiliary hoist,
pushing this switch will toggle the function of
the set of motor 1 pushbuttons between the
outputs for main and auxiliary hoist.
There are two red LEDs above this pushbutton
labeled “A” and “B”. The “A” LED comes ON
for the main function and the “B” comes ON for
the auxiliary. As the pushbutton is toggled the
sequence of outputs and LEDs is as follows.
Normally the main output only is active and the
“A” LED is lit. Pushing the pushbutton lights
only the “B” LED and the auxiliary output only
is active. Pushing the pushbutton a second time
lights both “A” and “B” LEDs and both main
and auxiliary outputs are active in tandem. (This
tandem operation can be disabled See Section 7-
8. tele
Pilot
Programming). When turning the
transmitter ON the default condition is always
“A”.
This pushbutton can be used with the Select
function also. When used for the Select function
the “A” and “B” LEDs work as described in the
above paragraph toggling the Select 1 output and
the Select 2 outputs respectively.

When the transmitter is ON the red LED flashes
slowly. When the unit transmits, the red LED
flashes rapidly. Top left indicator on tele

5-3. Low Battery Indication.
In the tele
Pilot
transmitter there is a separate
low battery indicator located to the right of the
ON/OFF indicator. This is a yellow LED that
turns ON solid when it is time to replace the
batteries.
For Membrane and Pedant transmitters if the
ON/OFF LED indicator does not light at all after
turning ON the transmitter or while operating
crane with the transmitter, replace the batteries,
they are weak. See Section 5-6. Battery
Replacement for battery replacement.
5-4. Optional 4th Motor Select
Indicator.
For two speed tele
Pilots
with four motors
programmed, this indicator will toggle between
“A”, ”B” and both (for units programmed with
or without tandem operation). Pressing the push
button directly beneath the indicators toggles the
state.
