9.2.2 Fault isolation relative to receiver parameter definitions or configuration
The safety receiver has two redundant electronic circuits integrating 4 microprocessors. For this reason, the fault
and error indications are divided into two groups on these 4 processors.
The 2 white indicator lights « V1 and V2 » indicate the state of the receiver safety functions.
o
Receiver state when transmitter is on its charger : "V1" On and "V2" Off.
o
Receiver state when transmitter is active : "V1 and V2" On.
Note : The states of indicator lights V3 and V4 is described in section 8.2.4.
In the event of a fault, at least one of the two indicator lights « V1 » or "run2 « V2 » is off, or both indicator lights
flash. In this case, they may even flash with different error codes (No.).

Communication
error
In the event of a serious communication error, the 2 indicator lights « V1 »
and « V2 » are off ; this is a serious error. The unit must be sent in for
repair.
5
Adjustment error
V1 and V2 flash 5 times: the 10-position switches for the 2 circuits do not
have the same positions.
6
Undervoltage or
overvoltage
V1 flashes 6 times: the power supply voltage is less than 0.85Un
V1 flashes 6 times: the power supply voltage is greater than 1.15Un
7
Short-circuit
One of the inputs is short-circuited
8
Safety relay error
V2 flashes 8 times : the return loop for terminals Y1-Y2 is not closed when
the safety outputs are inactive.
One of the output relays or its control circuit is defective.
9
Safety output
control error
The 2 controls for the safety relays do not correspond.
10
Software program
error
One of the processors has recognised an error in the running of its
program.
11
Parity error
The 2 processors take too much time to achieve the same state.
12
Version error
The software versions of the 2 processors do not match: the unit must be
sent in for repair.
13
Software memory
error
The software memory is defective. The unit must be sent in for repair.
14
RAM error
The processor working memory is defective. The unit must be sent in for
repair.
