Necessity of Purging
The following problems can arise if air or other gases remain in the air conditioning circuit. Be sure to perform purging the air conditioner circuit with a vacuum before charging with refrigerant (R134a).

1. Pressure rise in the high pressure side
If air remains in the air conditioner circuit, this disturbs the heat exchange between refrigerant and air in the condenser. This causes pressure to rise in the high pressure side (compressor side).
 

Refrigerant gas is easily liquefied, but air cannot be liquefied and remains as a gas in the condenser because the temperature at which air liquefies is extremely low. Therefore, liquidation of the refrigerant gas in the condenser decreases by the amount of air in the circuit, and the gas pressure in the high pressure side increases accordingly.
 

2. Metal corrosion
If air remains in the air conditioner circuit, a chemical reaction between refrigerant and moisture in the air takes place, and as a result, hydrochloric acid is produced. Hydrochloric aid corrodes metals such as aluminum, copper and iron.
3. Plugging of the expansion valve by moisture When high pressure refrigerant gas passes through the expansion valve, gas pressure decreases and temperature drops. Moisture included in high pressure refrigerant gas in the air conditioner circuit freezes at the expansion valve orifice, plugging refrigerant flow.
Operation of the air conditioner becomes unstable and cooling efficiency lowers.

How to Change Constant Speed for Deutz EMR3?

Here is the instruction show you guide on how to use Deutz SerDia2010 to change constant speed for Deutz EMR3 control unit.

To use this function, the engine has to be in fixspeed mode or the setting allows to activate the fixspeed mode.

 

Preparations:

2023 Deutz Serdia2010 v14.1.9.1 Diagnostic Software Free Download

Deutz Serpic EPC Parts Catalogue 2014 2012 Free Download

 

The actual setting for the fixspeed values are shown on the left upper part of the screen.
The setting of the switch is marked, too
Additionally the actual engine speed and the speed setpoint is shown as value and tachometer on the right side inclusive hysteresis to have a qualitative feedback.
 

Button "read from ECU":
The original stored values of the ECU were refreshed on the screen. Changes of the values are deleted.
Button "write values to ECU":
Values shown on the screen for fixspeed 2 (first intermediate speed) and fixspeed 3 (2. intermediate speed) are flashed to the ECU.
If the engine is still running while activation of this procedure, SerDia will ask to stop
engine automatically.
The values for fixspeed 1 (low idle) and fixspeed 4 (high idle) cannot be changed free,
because they are linked to low, respectively high idle. Textbox "Constant Speed 2","Constant Speed 3":
 

Changes in these textboxes have to be confirmed with ENTER.
After confirmation the new value will get active, if switched on (see marking point at fixspeed).
It is not possible to install a speed below fixspeed one or above fixspeed four.
The fixspeeds 1 and 4 are not changeable in this screen (see hints above).
