D-16 Planmeca Compact i
DETAILED DESCRIPTION OF ERROR MESSAGES
Technical Manual
E 36.n Pressure sensor error
Perform the same check as above.
E 36.1 Drive/Cooling air pressure sensor output >5V
E 36.2 Air coolant pressure sensor output >5V
E 36.3 Water coolant pressure sensor output >5V
E 36.4 Differential pressure sensor output >5V
E 37 Pressure sensor cable not properly attached to the IMUX
Cable is probably loose or not attached to the IMUX ribbon cable connector properly (all sen-
sor signals simultaneously out of bounds). Check also that the PSB is mounted properly so all
pressure sensor pins (4 x 4) mates with respective sockets. Check that the ribbon cable is
properly manufactured (connectors the right way around - pin 1 to pin 1). Check with a known
good PSB and replace the IMUX if necessary.
E 38 reserved
E 39 Drive (cooling) air valve control servo cannot maintain
pressure to instrument
The proportional valve gets full power but still the measured pressure does not reach the
required level. The most probable reason is that there is something reducing the air flow so
that the pressure cannot reach the level required even if the control valve is fully open. Check
for air tube kinks inside the unit and console arm. Check the condition of the incoming air
pressure regulator and also the air filter. Check that the incoming air pressure is within recom-
mendations. The control valve in the IMUX could also cause this problem. Replace the valve
as a last remedy.
E 40, 41 reserved
E 42 Air coolant (spray air) control servo cannot maintain
required pressure
The proportional valve gets full power but still the pressure measured does not reach the
required level. The most probable reason is that there is something reducing the air flow so
that the pressure cannot reach the level required even if the control valve is fully open. Check
for air tube kinks inside the unit and console arm. Check the condition of the incoming air
pressure regulator and also the air filter. Check that the incoming air pressure is within recom-
mendations. The control valve in the IMUX could also cause this problem. Replace the valve
as a last remedy.
