Installing the option modules

NOTICE
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.
NOTICE
A maximum of two option modules may be used at the same
time. The module types must be different.
NOTICE
If you are using the emergency shutdown module, the
module must be supplied with 24 V DC at terminals +85 / -
86. Otherwise, the positioner will not be able to function
pneumatically (device in pneumatic safety position).
NOTICE
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.-

Installing the mechanical position indicator

1. Loosen the screws for the housing cover and remove it.
2. Attach the extension shaft to the feedback shaft and
secure it using the screw provided.
3. Attach the round position indicator to the extension shaft
and rotate it into the desired position.
4. Attach the new housing cover (with round viewing window)
and screw it on to the housing. Tighten the screws so that
they are hand-tight.

6.5.2

Installing the mechanical position feedback

1. Loosen the screws for the housing cover and remove it.
2. If one has been installed, remove the optical position
indicator and unscrew the extension shaft.
3. Move the printed circuit board for position feedback to the
right underneath the two plastic clips and secure it using
the screw provided.
4. If applicable, install the optical position indicator.
5. Attach the housing cover and screw it on to the housing.
Tighten the screws so that they are hand-tight.
6.5.3

Installing the pressure option

CAUTION
Risk of injury
Risk of injuries due to flying components as well as
significant noise emissions.
Prior to disassembly, all connected compressed air lines
must be depressurized.
NOTICE
— The supply voltage must be switched off before the
pressure option is installed.
— The bond wires for the pressure option must not be
touched. Doing so will cause damage to the option
module.
— Before using the device, an IEC-compliant high-voltage
test must be performed.
