9.2.9 Options
Module for the emergency shutdown function
Supply voltage
24 V DC (20 ... 30 V DC)
(electrically isolated from input
signal)
Safe position is activated when
Voltage < 5 V
Explosion protection
see certificate (operating
instructions)
A separate 24 V DC signal is normally applied to the emergency
shutdown module, which connects through the signal from the
microprocessor to the I/P module.
When the 24 V DC signal is interrupted, the pneumatic module
executes the respective safety function, depending on the mechanical
construction:
The positioner output Y1 is depressurized, and the valve is moved to
the safe position. In case of a double-acting actuator the second
output Y2 is additionally pressurized.
IMPORTANT (NOTE)
The emergency shutdown module can only be used with
pneumatics with the safe position "fail-safe".
The emergency shutdown module works independently of the mother
board, i.e. all information from the final control element is available in
the supervisory process control system at any time.
