Installing the option modules
IMPORTANT (NOTE)
If you are using the "emergency shutdown
module", there must be a supply voltage of 24 V
DC at ter41 / -42. Otherwise, the
positioner will not be able to function
pneumatically (device in pneumatic safety
position).
IMPORTANT (NOTE)
A functional check of the "emergency shutdown
module" (option) must be performed at least every
2 years. For this purpose, the positioner must
move the valve into the safety position with the 24
V DC signal (ter85 / -86) interrupted.
