6.9 Controller information
The ‘Controller information’ screen shows the current hardware and software version, and
the serial number of the controller. This information can, for example, be used to check if the
correct version of the manual is being used as a reference. This information must also be provided
with each support request.
7 Alarms
If the machine detects an alarm or a warning a message will be displayed on the 2
nd
line of
the overview screen. In some cases, the numeric display above the graphical display will also blink
with the alarm number.
Alarms can be reset with the start button. Only one alarm is reset at a time so if multiple
alarms are active the start button must be pushed once for each alarm. The alarms are the messages
with number 1 to 24.
Warnings can also be reset with the start button but will also automatically reset if the cause
is solved. The warnings are the messages with number 25 until 30.
Status messages often do not require action. If a status message requires action this is
described in the explanation of the message. The status messages are the messages with number 31
until 40.
All alarms, warnings and messages which occurred can be checked in the alarm history
screen (see chapter 6.7).
The following alarms, warnings and messages can be displayed:
(1) Emergency stop
The input for the emergency stop and/or safety switches (input 10) is, or has been, in the
‘off’ state. This means the emergency stop has been pushed or one of the safety switches has been
activated.
(2) Overload protection
The input for the overload contacts (input 4) is, or has been, in the ‘off’ state. This means
one of the overload protections is activated.
(3) Error frequency inverter
The input for the error of the frequency inverter (input 11) is, or has been, in the ‘off’ state.
This means that (one of) the frequency inverter(s) gives an error signal.
(4) Error inverter synchronization
The input for the error of the frequency inverter (input 11) is configured to be a ‘pulse train’
input. This means that the controller must detect a certain pattern on this input signal. If not, the
machine is stopped out of safety issues because if this pulse train is not detected, a malfunction of
this signal can be possible.
(5) Control panel blocked
In some circumstances, it is possible that the controller locks itself. If this happens, an
unlocking code must be entered. This can be done via the ‘System Setup’ menu (see chapter 6.6.5)
or by switch the controller off and on again. In the ‘Enter unlocking code’ screen, the unlocking
code can be entered. Contact the manufacturer for the right unlocking code.
