Installing the option modules
IMPORTANT (NOTE)
The supply voltage must be switched off before
the option modules are installed.
1. Loosen the screws for the housing cover and remove it.
2. Position the option module so that the plug points to the
right.
3. Using a small amount of pressure, guide the option
module into the slot from the side and press it down
firmly.
4. Secure the option module in the housing by tightening the
screw so that it is hand-tight.
5. Attach the housing cover and screw it on to the housing.
Tighten the screws so that they are hand-tight.
6. If you are using the emergency shutdown module, the
rotary switch on the main printed circuit board must be
rotated into position 1 using a suitable flat-bladed
screwdriver.
7. Attach the housing cover and screw it on to the housing.
Tighten the screws so that they are hand-tight.

IMPORTANT (NOTE)
A maximum of two option modules may be used
at the same time. The module types must be
different.
IMPORTANT (NOTE)
If you are using the emergency shutdown module,
the module must be supplied with 24 V DC at
terminals +41 / -42. Otherwise, the positioner will
not be able to function pneumatically (device in
pneumatic safety position).
IMPORTANT (NOTE)
Perform a functional check of the emergency
shutdown module (option) at least every 2 years.
For this purpose, the positioner must move the
valve into the safety position with the 24 V DC
signal (terminal +85 / -86) interrupted.
