Pos: 79 /Aufbau und Beschreibung/ES 2 - Steuerung/Fehlermeldungen/Fehler 13 Motordrehzahl überschritten @ 1\mod239_2.docx @ 4004 @ @ 1
Fault 13
Max. rpm exceeded

Max. rpm. of the engine has been
exceeded by 10 % or more (5 sec.).
Only in pressure control mode:
Incorrect (too large) nozzle(s).
Too much bypass water (incorrect
PRV setting)
Wear in the bypass / PRV .
Readjust the linear motor. 
After exchanging the linear motor at
idle speed.
Pos: 80 /Aufbau und Beschreibung/ES 2 - Steuerung/Fehlermeldungen/Fehler 14 Motortemperatur zu hoch @ 1\mod113_2.docx @ 4028 @ @ 1
Fault 14
High engine temp

High engine temperature
Check coolant water level.

Cooler blocked
Check cooler

Ventilator defective
Check ventilator

Air supply or air outlet blocked.
Check the openings of air supply and air
outlet.
Pos: 81 /Aufbau und Beschreibung/ES 2 - Steuerung/Fehlermeldungen/Fehler 15 Druckaufnehmer defekt @ 1\mod114_2.docx @ 4092 @ @ 1
Fault 15
Defective pressure
sensor

Pressure sensor defective
Check the. 4 mA in the operators menu.
If 0 mA the bypass socket or wiring to
socket is faulty. Check the socket for
short circuit.
If bypass socket is O.K
If voltage is approx. 22 volts but 4
mA current is not present replace the
transducer.
Pos: 82 /Aufbau und Beschreibung/ES 2 - Steuerung/Fehlermeldungen/Fehler 16 Luftdruck zu gering @ 1\mod115_2.docx @ 4032 @ @ 1
Fault 16
Low air pressure

Min. air pressure < 5 bar
Shut off high pressure
air pressure > 5 bar,
automatically reset fault.
Check pneumatic installation
Check pressure switch/sensor
sensor power

4 mA
if necessary exchange.
If an air filter is dirty, the air flow will be is reduced.
This will result in the air pressure behind the filter crashing briefly when the high pressure is
activated, since only a small amount of air can flow through the filter.
If it takes too long for the air pressure behind the filter to stabilise, a unit with air pressure
monitoring will switch off giving an appropriate error message "air pressure too low".
Only one warning will be shown on the display of the ES2 and the high pressure will be switched
off. The engine will continue to run at idle (no air pressure can be built up without a running
engine!)
The warning will disappear however as soon as the air pressure is OK again.
