B13 PMC Positive of the main contactor.
B14 KEY OUT Output of the Key switch signal.
B15 NOT USED Free.
B16 PEB Positive of the electromechanical brake.
B17 PEVP Positive of the proportional electrovalve.
B18 PEV2 Positive of the electrovalve 2.
B19 PEV1 Positive of the electrovalve 1.
B20 PEV4 Positive of the electrovalve 4.
B21 PEV3 Positive of the electrovalve 3.
B22 PEV5 Positive of the electrovalve 5.
Note:
Proportional valve can be programmed by console as proportional or ON/OFF: if
proportional the valve has an acceleration and deceleration ramp and its current is
controlled by the lifting potentiometer.
If ON/OFF the valve is completely opened/closed without ramps.
The positive supply to the main contactor is provided from the key (pin 12) trough a
diode against polarity inversion. The positive supply for the electrobrake is available in
the pin 16 only if the tiller switch is closed.
The positive for the brake and all the other ON/OFF valves comes from the main
contactor, so these loads do not affect the key input but only the auxiliary fuse.
3.3.3 Connector "C" description
The "C" connector manages the serial link of the tiller card.
C1 -BATT Negative free for the customer.
C2 BELLY Quick inversion microswitch input. This signal is directly connected
with the Combi for safety reason.
C3 SNAIL + T Snail microswitch input. It is necessary that the tiller microswitch is
cabled in the serial tiller card; in this case it is possible to run the
truck also with the handle released at a slow speed.
C4 TILLER Tiller microswitch input. In this case the tiller is directly connected
with the Combi.
C5 DRFT Data from the serial tiller
C6 -BATT Negative for the serial tiller card.
C7 KEY OUT Positive for the serial tiller card (is a key switch signal).
C8 KEY OUT Positive for the tiller microswitch (is a key switch signal).
Note:
The tiller microswitch can be cabled in the serial tiller (see ‘serial tiller’ drawing) or
directly in the controller (PIN 4 and 8 for the key in the serial tiller).
