“LAN” INTERUPTED ALARM
Indicates problems of communication between units in the LAN and
specifies which units are not connected. This may be due to a break in
the power supply, a malfunction in the serial card or an interruption in
the electrical connections between the units.
The alarm appears on the units with lower addresses in the network,
both up and downstream of the interruption.
SYSTEM ALARMS
Indicates a writing error in the EEPROM memory, probably due to the
cancelling/writing cycle being exceeded. The board needs to be
replaced.
ACCESS ALARMS
This refers to an attempt at accessing the setting or configuration
screens by entering the password incorrectly 3 consecutive times.
NOTE:
To reset the alarm, carry out the following procedure:
1. press
the
Prg key and select the Service Menu;
2. enter the correct password and confirm by pressing Enter;
3. exit by pressing the Esc key until the main screen is reached;
4. press
the
Alarm key again to reset the cycle and then keep it
pressed for another 3 seconds to reset the alarm completely.
REMOTE ALARM SIGNALLING
For remote signalling of the alarm status, the following voltage free dry contacts are available on the
microprocessor control board (see electrical diagram attached):
1. type A alarm
2. type B alarm
If there are several units, the wiring of the dry contacts must be carried out independently for each unit.
To select the type A or B and the state of the contact, enter the Parameter Menu and choose the Alarm Contact
option.
