5.4 Checking the peripheral
devices
The peripheral devices can be tested as follows:
Temperature and pressure sensors
The two sensors are working properly if, in the regulation mode, the
displayed measured values of the evaporation temperature TO and
the suction gas temperature TOH are realistic (reference measure-
ments). If internal capacity control is configured, the sensor for the
medium temperature must also be checked. For potential faults,
refer to chapter 7.
Electronic injection valve
In the simulation mode, you can pre-set an opening degree (MAN
EIV) for the electronic injection valve. In the same mode, you can
check if the actual position of the value (EIV) matches the manual
set position (MAN EIV)
It should be noted that a small difference between positioning signal
and position feedback signal is the rule, but the difference should not
significantly vary over the entire positioning range.
