Step 4: Air Connections
1. Connect Out 1 Port on Gauge Block to Actuator Inlet
2. Connect Air Source to In Port on Gauge Block (Recommended
Air Pressure 70-90 PSI, 90 PSI max. Coalescing fi lter must be
used on supply air)
3. Gauges are pre-mounted on Gauge Block
Step 5: Electrical Connections
• Terminals +11 and -12 used for 4-20mA Analog Input
• Terminals +31 and -32 used for 4-20mA Feedback Loop
24VDC Powered Analog Output

COMMISSIONING:
Option 1: Using the Pushbuttons and LCD Display on the
Positioner
1. Feed in Air Pressure
2. Feed in electrical supply power
• Feed in setpoint current 4-20mA (terminals +11/-12)
3. Check mount:
• Press and hold
Mode
, plus
↑
or
↓
until operating mode
1.3 (manual adjustment within the sensor range) is displayed.
Release
Mode.

and then
↓
simultaneously to
move in one direction and then

ADJ_ROT
is displayed;
release the
Enter
button
• Press
Enter
again and hold down until the countdown ends
• Release
Enter
; this starts Autoadjust
The Autoadjust process may take up to 5 minutes to fi nish,

within the sensor range). The mount is checked and corrected
if necessary. Autoadjust then runs again.
Option 2: Using a HART Communicator
1. Feed in Air Pressure
2. Feed in electrical supply power
• Feed in setpoint current 4-20mA (terminals +11 / -12)
3. Connect HART communicator to terminals 11 and 12 coming
from the positioner
4. Go online with the communicator.
Then go to Settings
