The following parameters can be set in the configuration mode:
bay unit network address (ranged 1....99)
association of the protected zones with the corresponding detectors.
There are 3 available options:
detector no. 2 configured to work in zone 1,
detector no. 2 configured to work in zone 2,
detector no. 2 configured to work in zone 3,
detector no. 2 off.
From the level of this menu one can run optical detectors test. The procedure is described in

11.4. Error messages
In case when a bay unit will detect wrong operation of the device error number will be
shown on the display.
„E1”
no communication with the central unit. The bay unit works in “single criterion” mode.
A tripping signal is generated in case of an optical module activation (U< module activation
may not checked). Tripping is only possible in zone 2 and in zone 1 (isolated operation).
„E2”
permanent activation of the optical module (activation of one of the optical detectors for
longer than 5 s) The protection does not detect any voltage drop. The detection channel that
has been activated permanently is now set
“off”. If the cause of activation disappears, the
device will return to its normal “ready” status and “ERROR” LED will stop lighting.
„E3
a bay unit has its network address configured incorrectly. A physical connection
through CAN interface is correct. It is necessary to register this bay unit in the central unit.
“ERROR” LED is not lighted.
„E4”
A bay unit does not have either a network address or a serial number assigned.
