Installing The Mechanical Position Feedback; Installing The Pressure Option; Setting The Mechanical Position Indication - ABB PositionMaster EDP300 Manual

PositionMaster EDP300 DIGITAL POSITIONER | CI/EDP300-EN REV. D

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
indication and unscrew the shaft extension.
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 indication.
5. Attach the housing cover and screw it on to the housing.
Tighten the screws so that they are hand-tight.

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.
Note
• The supply voltage must be switched off before the pressure
option is installed.
• The bonding wires for the pressure option must not be
touched. Doing so will cause damage to the option module.
• Before using the device, a high-voltage test in accordance
with IEC must be performed.
