3) If step 2) was fulfilled, then P1 is probably OK. Perhaps also check that P1 LED remains
ON during raising of the plate even with maximum weight set-up. If this is OK too, then
you may proceed with P2 check below.
If step 2 failed, this may be due to any of three causes:
4) Defective Wiring: Disconnect one of the two P1 wires directly on the switch. This must
cause P1 LED to turn OFF. If so, go to step 5). If not, check cable to the Compact 15.
Connect again P1.
5) Too low Excess Pressure: If the hyd. pump excess pressure has not recently been
checked/adjusted, then perform this (refer to 11.3.2, “Adjusting the Hyd. Pump Excess
Pressure”).
6) P1 is defective and should be replaced.
17.11.2 P2 check:
9) First check P2 wiring and the P2 LED: if P2 LED is ON, then press LC button for some 2
seconds (catch should be low), which must cause P2 LED to turn OFF (if P2 LED WAS
OFF, then go to step 10).If P2 LED will NOT turn OFF, then disconnect one of the P2
wires directly on the P2 switch, which must cause P2 LED to turn off, otherwise check
P2 cable to Compact 15. Connect again P2.
10) If the P2 LED is OFF, then raise the weight (to any height), which MUST turn ON the P2
LED.
If the P2 LED will NOT turn ON, then short-circuit the P2 terminals, which must cause
P2 LED to turn on, otherwise check P2 cable to Compact 15.
WHEN the above steps 9 and 10 check out OK, perhaps after exchange of P2, then make
a final check as follows:
11) Drop the weight and raise the catch completely.
12) WHILE WATCHING the P2 LED, press the LC button and check that the LED is ON
AND REMAINS ON AS LONG AS THE CATCH IS MOVING DOWNWARDS, AND
that it turns OFF very shortly (max. 0.5 sec.) after the catch has reached its bottom
position (the LC button should be kept pressed until P2 turn-off, unless this is delayed too
much). Perhaps repeat once or twice. If this check fails, replace P2.
13) Raise the weight (to any height) and check that P2 LED is ON. This must also apply for
minimum weight package. If NOT, replace P2.
