On the receiver the green light indicates that a signal is being
received, the red indicates the status or error. Below are a list of the
error codes both as they would be displayed on a Palm handheld and
on the receiver.
CODE (Receiver/Palm): 1 Flash/EC01
DESCRIPTION: Signal problem
POSSIBLE CAUSE(S): No signal from transmitter/pendant or transmitter power off.
POSSIBLE SOLUTION(S): Check transmit light on transmitter, light should flash when
function is activated. If light does not flash, make sure
transmitter is on. If light flashes and red low battery light is
flashes, charge unit. If transmitter is plugged in as a
pendant and transmit light comes on but code remains,
check cable connections and cable.
CODE: 2 Flashes/OVL
DESCRIPTION: Overload
POSSIBLE CAUSE(S): Pressure overload.
POSSIBLE SOLUTION(S): Retract boom, hoist down or otherwise alleviate overload
condition. Refer to load chart for rated load. If the error
persists with seemingly light loads, install pressure gage in
plugged port of lift cylinder counterbalance valve to confirm
pressures in excess of 1,900 psi.
CODE: 3 Flashes/A2B
DESCRIPTION: Anti-two block
POSSIBLE CAUSE(S): Anti-two block switch tripped.
POSSIBLE SOLUTION(S): Check switch, if not mechanically tripped, check continuity
cross switch at plug. If switch has continuity check voltage
across transmitter side of A2B plug. If low voltage is read,
power to the A2B switch, the rotation switches or the
pressure sensor may have a short.
