Description
Variable or constant.
Activation of the FB. Initial value is FALSE.
This parameter can be connected to the variable, which represents the
status (active or not active) of the relevant safety device. This ensures no
irrelevant diagnostic information is generated if a device is disabled.
If FALSE, all output variables are set to the initial values.
If no device is connected, a static TRUE signal must be assigned.
Variable or constant.
FALSE (= initial value): Manual reset when PES is started (warm or cold).
TRUE: Automatic reset when PES is started (warm or cold).
This function shall only be activated if it is ensured that no hazard can occur
at the start of the PES. Therefore the use of the automatic circuit reset fea-
ture of the function blocks requires implementation of other system or appli-
cation measures to ensure that unexpected (or unintended) start-up does
not occur.
