Condenserless water-cooled water chillers

Consulting actual operational information
The actual operational information that can be consulted in the list of
direct parameters consists of:
■ b01: Evaporator inlet water temperature,
■ b02: Evaporator outlet water temperature,
■ b03: When cooling mode is active: inlet water temperature of
the condenser. When heating mode is active: inlet water
temperature of the evaporator.
■ c10: Total running hours of the compressor 1,
■ c11: Total running hours of the compressor 2,
■ c15: Total running hours of the pump.
These are direct parameters, refer to "How to consult and modify the
direct parameters" on page 8.
Resetting alarms
When an alarm is detected, the following happens:
■ the alarm relay is energized,
■ the H LED is displayed
■ the display starts flashing, alternately showing the alarm code
and the inlet water temperature.
The following alarm codes may appear on the screen:
■ a1: indicates an anti-freeze alarm.
■ e1: indicates that the NTC probe used to measure the
evaporator inlet water temperature is defective.
■ e2: indicates that the NTC probe used to measure the
evaporator outlet water temperature is defective.
■ e3: indicates that the fuse for the evaporator heatertape (F4)
is blown or that there is a reverse phase error or that there
is a problem with the I/O PCB (A2P).
■ ehs: indicates that the supply voltage is exceedingly high. In
this case contact a licensed electrician.
■ el1: indicates that there is a power supply error (example:
noise). In this case contact a licensed electrician.
■ el2: indicates that there is a power supply error (example:
noise). In this case contact a licensed electrician.
■ els: indicates that the supply voltage is exceedingly low. In this
case contact a licensed electrician.
■ epb: indicates that the EEPROM on the controller PCB inside
the unit is defective.
■ epr: indicates that the EEPROM on the controller PCB inside
the unit is defective.
■ fl: indicates that there was no sufficient water flow either
during the period of 15 seconds after the pump was
started or for 5 seconds while the compressor is active or
that the overcurrent protection of the pump is activated.
■ hp1: indicates that a high pressure switch, the discharge
thermal protection or the overcurrent protection of the
compressor motor is activated or that the NTC probe used
to measure the ambient temperature is defective.
■
fl + hp1
: indicates that there is most likely an RPP error or that the
F4 fuse is blown.
■ lp1: indicates that the low pressure switch is activated.
■ ter: indicates that there is a remote user interface
communication error.
■
:
communication failure between the digital controller of the
unit and the remote user interface. Confirm the correct
selection of parameter code h23. This should be default
setting 0 and confirm the correction installation according
to the installation manual of the remote user interface
EKRUMCA.
To reset an alarm, proceed as follows:
1 Find the cause of shutdown and correct.
Refer to the chapter "Troubleshooting" on page 15.
2 If the alarm codes a1, fl, hp1 or lp1 appear on the display,
reset the alarm manually by pressing the E combination keys
C and D simultaneously for approximately 5 seconds.
In all other cases the alarm is reset automatically.
Once the alarm is reset, the error code and the H LED no longer
appears on the display. The controller continues its normal
operation, displaying the inlet water temperature.
Resetting warnings
During normal operation, the display of the controller may start
flashing, alternately showing the inlet water temperature and the
following warning code:
■ hc1: indicates that the compressor 1 requires maintenance:
the total running hours of the compressor 1 (direct
parameter c10) has exceeded the setting of the timer
threshold for maintenance warning (user parameter
c14).
■ hc2: indicates that the compressor 2 requires maintenance:
the total running hours of the compressor 2 (direct
parameter c11) has exceeded the setting of the timer
threshold for maintenance warning (user parameter
c14).
To reset the maintenance warning hc1 or hc2, proceed as follows:
1 Consult c10 running hours of compressor 1 or c11 running
hours of compressor 2.
These are direct parameters, refer to "How to consult and modify
the direct parameters" on page 8.
2 When c10 or c11 parameter value is displayed, press the
C and D key simultaneously for 5 seconds. The value of
the timer becomes 0 and the warning is reset.
NOTE
■ The parameters b01, b02 and b03 can also be
consulted by the "sensor readout menu". Refer to
"How to consult the "sensor readout menu"
parameters" on page 8.
■ To reset the timers of parameters c10, c11 and
c15 refer to "Resetting warnings" on page 9.
In case the unit is equipped with freeze protection, it is
highly recommended to install the remote indicator
lamp alarm (H3P) (see wiring diagram supplied with
the unit). By doing so, breakdown of the fuse for the
evaporator heatertape (F4) will be detected sooner
and freezing of the circuit will be avoided during cold
weather.
NOTE
If the alarm codes fl and h1 are flashing alternately,
the alarm is most probably caused by the reverse
phase protector or by the fuse for evaporator heater-
tape (F4) that was blown.
NOTE
Do not forget to carry out the required maintenance
activities after resetting the timers.
Besides resetting timer c10 and c11, it is also
possible to reset timer c15 (running hours of pump) in
the same way.
