Tasks of the safeties menu
Listing activated safeties and checking the unit status
If the alarm buzzer is activated and the user presses the p key, the
controller automatically enters the safeties menu.
■ The controller will enter the
screen of the safeties
menu when a unit safety was the cause of shutdown.
■ The controller will enter the
screen of the
safeties menu when a safety of the circuit was activated.
■ For a DICN system, the controller can also show:
&
. This occurs when the wrong
number of slave units is defined (refer to "Defining the network
settings" on page 12) or when a slave unit is missing (because
of bad connection or power supply failure).
Make sure to define the correct number of slave units and to
make correct connections.
■ When the unit is configured with a dual evaporator pump, the
controller will enter the
screen of the
safeties menu when a safety on the pump was the cause of
shutdown.
1 Press the p key when the alarm buzzer is activated.
The appropriate safety screen with the basic information
appears. Press the q key to see the detailed information. These
screens provide information about the unit status at the moment
of shutdown (see "Safeties menu" on page 10).
2 If more than one kind of safety is active (indicated by means of
W, X or C), use the g and h keys to consult them.
Tasks of the history menu
Checking the safety info and the unit status after a reset
The information available in the safeties menu is also stored in the
history menu, where it is stored after resetting the unit or the circuit.
In this way, the history menu provides a means of checking the unit
status at the moment of the latest shutdown.
To check the safety info and the unit status, proceed as follows:
1 Enter the
. (Refer to the chapter "How to enter a
menu" on page 6.)
The controller enters the last
screen which contains
basic information of the moment of this shutdown.
2 Press the g and h keys to consult the other present
screens.
3 Press the q key to see the detailed information.
Tasks of the info menu
Consulting additional unit information
1 Enter the
through the main menu. (Refer to the
chapter "How to enter a menu" on page 6).
The controller enters the
screen which
contains the following information: the time and date.
2 Press h to consult the first
screen.
This screen contains information about the unit name and the
refrigerant used.
3 Press h to consult the next
screen.
This screen contains information about the controller's software
version.
4 Press h to consult the
screen.
This screen contains information about the PCB.
Tasks of the input/output menu
Checking the status of the inputs and outputs
The input/output menu provides a means of checking the status of
the digital inputs and the status of the relay outputs.
The locked digital inputs are:
■
: whether the emergency button has been
pressed.
■
: indicates the status of the flowswitch: activated or
deactivated.
■
: indicates the actual status of this
safety.
■
: indicates the actual status of
this safety.
■
: indicates the actual status of this safety.
■
: indicates the actual
status of this safety.
■
: indicates the actual
status of this safety.
The changeable digital inputs are:
■
"#
: indicates the position of the "enable/disable
capacity limitation" switches.
■
: indicates the position of the remote dual
setpoint switch: setpoint 1 or setpoint 2.
■
&
: indicates the position of the remote on/off switch.
■
: indicates the position of the connected switch.
The locked relay outputs are:
■
: indicates whether the circuit is on or off.
■
: indicates whether the circuit is in starmode
or not.
■
: indicates whether the circuit is in deltamode
or not.
■
*
: indicates if the 12% capacity valve of the circuit is
activated.
■
: indicates if the
of the capacity control motor of the
circuit is activated.
■
: indicates if the
of the capacity control motor of
the circuit is activated.
■
: indicates the
of the potentiometer of
the circuit (Ω).
■
: indicates if the fans of fanstep 1 for the circuit
are on or not.
■
: indicates if the fans of fanstep 2 for the circuit
are on or not.
■
"
: indicates if the fans of fanstep 3 for the circuit
are on or not.
■
: indicates the status of this voltage free contact. It
is activated if the pump should be ON.
■
&
: indicates the status of this voltage free contact. It
is activated if there is any alarm on the unit.
■
&
: indicates the status of the evaporator heater.
The changeable relay outputs are:
■
: indicates the status of the second evaporator
pump.
■
%%*
: indicates when the unit is working at 100%.
■
: indicates the status of the 3-way water valve
when the unit is in free cooling state.
■
: indicates the closed status of the changeable
digital output.
NOTE
You can check the "found" slave units in the 2nd
screen of the network menu.
