Figure 8. Acceptable Mounting Positions.
The vertical position is the recommended position for mounting. Other positions are
allowed. When using the Weather Shield for NEMA 3R rating, the vertical position is
required. See Weather Shield installation instructions and Figure 8.
Allow four inches (100 mm) around the sides and back of the actuator and eight inches
(200 mm) above and to the front of the actuator.
See dimensions in Figure 17.
Detailed installation instructions for field mounting are shipped with the actuator.
Check the wiring for proper connections.
NOTE:
The valve body assembly determines the complete assembly action.
To determine the stroke positions 0% and 100% in the valve, calibration is required
when the valve/actuator are commissioned for the first time.
The actuator must be mechanically connected to a valve and must have a 24 Vac
power supply. The calibration procedure can be repeated as often as necessary.
CAUTION:
Before starting calibration, be sure the manual adjuster
is set to Automatic to register the actual values.
There is a slot on the printed circuit boards of the actuators. To
initiate the calibration procedure, the contacts inside this slot
must be short-circuited, for example, with a screwdriver
(see Figure 9).
Automatic calibration proceeds as follows (see Figure 10):
·
Actuator runs to the 0 stroke position (1), green LED flashes.
·
Actuator then runs to the 100 stroke position (2), green LED
flashes.
·
Measured values are stored in the EPROM.
·
The actuator now moves to the position defined by control
signal Y or Z (3), and the green LED now glows steadily
(normal operation).
·
Throughout this procedure, output U is inactive; meaning,
the values only represent actual positions when the green
LED stops flashing and remains on continuously.
