Hi there can anyone help me with a v200 max
I am a fridge engineer. I have a v200 max showing PSE when you switch on. There is gas in system(5bar).
PSE High Pressure Sensor Fault
1. This alarm code indicates that the signal from the HP
sensor is outside of the readable range (<0.5 Vdc [at 0
psi] or >4.5 Vdc [at 500 psi]), and that a fault exists
with the high discharge pressure sensor.
2. Inspect for a blocked or dirty condenser coil.
3. Inspect for a faulty High Pressure transducer.
4. Check that pin C4 at connector C-1 on PCB 1 is
connected (check for a pushed pin or loose pin crimp),
not corroded, and is not obstructed by dirt.
5. Observe the continuity between CHT (pin C2,
connector C-1) and the ground bolts.
6. Make sure that the voltage between pins C3 and C4 on
connector C-1 corresponds to the table below.
7. Check for +5 volts at pin C5, connector C-1 on PCB 1. There is only 1,6V
8. If the problem persists, replace the terminals in the
connectors of the ECM and the transducer.
9. Outside the main harness, connect the transducer
directly to the ECM.
ALARM CODES, THEIR CAUSES AND CORRECTIVE ACTIONS (continued)
Code Cause or Explanation Corrective Action (check in order shown)
Pressure
(PSI)
Output Voltage
(HP-CHT) (V)
130 1.4
180 1.8
200 1.9
300 2.7
450 3.9
Is there anyway of bypassing transducer to see if its the cause?
I dont want to have to replace board if possible.
Does anyone have a manual?
I know how thermo king are about manual but i wont be passing it on only want it to fix my own unit.
