3.3.2 Non-testable sensors

When DIP switches 1 and 5 are set as shown, the sensors are
not tested. The non-testable sensors include all other sensor
types not mentioned in the preceding subsection. On non-
testable sensors the sensor output signal is "HIGH "in the
active state. The following safety rules apply to the use of non-
testable sensors:
Ÿ On power-up all muting sensors must be inactive, otherwise
the muting indicator lamp will flash at 2 Hz (twice per
second).
Ÿ With continuous muting concurrence monitoring of the
muting sensors must be selected.
Ÿ The cables between the MSM and the sensors must be laid
appropriately to avoid crossed connections between the
cables of the sensors of one pair.
