E. Testing proportional valves (P1---P5) in the test mode in AC 5.2
Note! When the pro portional valves are tested, all solenoid outputs are connected automatically unenergised.
Hint! E.g. value P4 1.8 means, that the forward direction proportional valve takes max. current of 1,8 A (in the test mode).
Example:
P1=DPS
proportional
valve no 1
(C1)
Module A=AC 5.2
1.2=value within given

--- If LO=wire damage
* Although the current value is between the limiting values, can fault codes P101...P109 appear. In that case t he AC5 ---con-
trol unit must be re---programmed with a new main program file ( versions 86) and the suitable parameter file (see page
370/24G). Newest program versions 83...86 allow a litt le higher current values, because the higher curr e nt taken by a cold
sole noid could cause a fault code.
--- If one of the values in the diplay deviates from the given values, measure the solenoid resistance on the connector X13 pins
or direct on the valve pins. Check that the pins are not loose (see instr. C on page 370/21). If the resistance is correct, but the
display reading is faulty, the fault lies in the wires.
Measure also the supply voltage o f the control unit while t he engine is running (1500 rpm). Correct value is 12 V ---14,8 V.
--- If the solenoid resistance was faulty, the solenoid is damaged and should be changed. When the propor tional valve o r the
solenoid is changed, the valve indexes must be checked (see page 370---24D).
If above mentioned points are OK, faulty current value can be caused by a defect AC5.2 control unit A1.
Note! Resistance measures and dio de checks, see instr. 4C on page 370/21.
Important! Be careful not to mix up the proportio nal valves and normal solenoid valves during repair work.
WARNING! The proportional valves have a pin for a manual use, which MUST NOT be manipulated: the tractor may sudden-
ly star t to move, or the pin can become trapped and can cause later damage to e.g. multi---disc cl utches. That is why it must
always be checked after the repair work (before engine start), that the proportional valve spools are in the outer positions i.e.
almost flush with the valve body (if not, remove the valve and press the spool so that the “manual pins” rises).
