Output for the OTE (Output Test Equipment)
Activation: this is necessary for category 2 configurations for signaling dangerous fail-
ures as per EN 13849-1: 2006 / DAM1 (in preparation).
OTE output: normally ON. If there is a fault in the internal feedback or the external de-
vice monitoring (EDM) => OFF. This signal makes it possible to stop hazardous move-
ments, or at least to indicate the fault to the operator.
Usage of the automatic start (A) or manual start (B) (category 2)

Category 4. Outputs with a two category 4 relays. Each
module AZ-FO4/AZ-FO4O8 can have up to two of these
outputs. The relays are operated in pairs for this out-
put.
Properties:
2 dual-channel outputs.
Double internal relays are monitored.
Each output can be set to manual or automatic start-
ing.
To avoid affecting the result of the calculation of the PL, the inputs (sensors or safety
components) must correspond to the same or a higher category as the other devices
in the chain.
