MODEL AGZ CHILLERS
Pump Control Keys
Operation Control Keys for local control are found at the
bottom of the control panel. The key in use will have an LED
illuminated above it.
Figure 92: Pump Control Keys
Hand On
Enables control of the pump speed via the graphic keypad.
It will over-ride any other mode setting. Raise or lower the
frequency (speed) using the up and down arrow keys. The
pump will run even without a start signal from the chiller. If
selected when in the Auto mode, it will start operation at the
current speed. When going back to Auto, it will be at the last
Hand on speed, but quickly return to the correct automatic
speed.
NOTE: The low water device (flow switch) input must be
made for the pump to start in either hand mode or
auto mode.
Off
Stops the pump in any operating mode.
Auto-On
Enables the pump to be controlled by either the sensorless
control, the BAS or by the remote pressure sensor, depending
on which operating mode is being used. When a start signal is
applied on the control terminals the pump will start.
NOTE: For the pump to operate in either Sensorless mode or
any other automatic control mode it is necessary to
have pressed the [Auto on] button.
Reset
Used for resetting the frequency converter after an alarm (trip).
Warnings and Alarms
A warning or an alarm is signaled by the relevant LED on the
front of the GLCP and indicated by a code on the display. A
warning remains active until its cause is no longer present.
Under certain circumstances operation of the pump may still
be continued. Warning messages may be critical. Warnings
should be attended to ASAP as they can revert to an Alarm-
shutting down the unit.
Viewing Warnings & Alarms
To view the warning or alarm details, press the Alarm Log key
in the middle of the GLCP. Press the ▲ or ▼ key to go to the
Alarm Log line and press OK. Navigate to the appropriate
alarm number, press OK and view the alarm description,
number and date-time stamp. A detailed description with some
corrective measures is below in the section titled Warning/Fault
Messages.
Resetting Alarms
In the event of an alarm, the inverter will have tripped. Alarms
must be reset to restart operation once their cause has been
rectified. In many cases the auto reset function will restart the
pump. Alternatively the [RESET] button on the control panel
can be pressed.
NOTE: After a manual reset using the [RESET] button on the
control panel, the [AUTO ON] button must be pressed
to restart the pump.
If an alarm cannot be reset, the reason may be that its cause
has not been rectified, or the alarm is trip-locked.
Alarms that are trip-locked offer additional protection, means
that the mains supply must be switched off before the alarm
can be reset. After being switched back on, the inverter is no
longer blocked and may be reset as described above once the
cause has been rectified.
Alarms that are not trip-locked can also be reset using the
automatic reset function Reset Mode (Note: automatic wake-up
is possible!)
Selected warning and fault messages follow.
Warning/Fault Messages
WARNING/ALARM 3 - No motor
No motor has been connected to the output of the inverter.
WARNING/ALARM 4 - Mains phase loss
A phase is missing on the supply side, or the mains voltage
imbalance is too high. This message also appears in case of
a fault in the input rectifier on the inverter. Check the supply
voltage and supply currents to the inverter.
WARNING/ALARM 9 - Inverter overloaded
The inverter is about to cut out because of an overload (too
high current for too long). The counter for electronic thermal
inverter protection gives a warning at 98% and trips at 100%,
while giving an alarm. You cannot reset the inverter until
the counter is below 90%.The fault is that the inverter is
overloaded by more than nominal current for too long.
WARNING/ALARM 10 - Motor ETR over temperature
According to the electronic thermal protection (ETR), the
motor is too hot. You can choose if you want the inverter to
give a warning or an alarm when the counter reaches 100% in
programming par. 1-90 Motor Thermal Protection. The fault is
that the motor is overloaded by more than nominal current for
too long. Check that the motor in programming par. 1-24 Motor
Current is set correctly.
WARNING/ALARM 11 - Motor thermistor over temp
The thermistor or the thermistor connection is disconnected.
You can choose if you want the inverter to give a warning or
an alarm in par. 1-90 Motor Thermal Protection. Check that the
thermistor is connected correctly between terminal 53 or 54
(analog voltage input) and terminal 50 (+ 10 Volts supply), or
