Commissioning
M9106-AGx-2N0x
After wiring is completed, apply power to the controller
and provide signals to the actuator to drive it at least
one complete cycle open and closed.
DPT-2015
To commission the transmitter:
1. Perform the checkout procedure provided in the
controller installation instructions,
DPT-2015
Differential Pressure Transmitter for VAV Box
Applications Installation Instructions
(Part No. 24-7547-18)
, to ensure proper operation
of the transmitter.
IMPORTANT:
Perform commissioning when
the transmitter is permanently mounted and
operating at normal temperatures.
2. Set up and zero using HVAC PRO
software
when using a DPT-2015 with a Johnson Controls
VAV Series controller. Refer to the
Variable Air
Volume Controller Technical Bulletin
(LIT-6363040)
for details.
Troubleshooting
M9106-AGx-2N0x
If the actuator is not responding or working properly:
•
Verify that the actuator assembly is properly
secured to the duct.
•
Check that all electrical connections are complete
and power is applied.
•
Verify that the damper fully opens and closes,
using the gear release lever on the actuator.
•
Check that the actuator stroke is set for the
desired application.
DPT-2015
The DPT-2015 must be auto zeroed by a
Johnson Controls VAV controller. If the DPT-2015 is
not operating properly:
•
Verify that the air lines on the DPT-2015 are
connected to their respective high and low ports
with no kinks in the tubing.
•
Check the supply voltage to ensure it is within the
14.5 to 17 VDC range and the polarity is correct.
•
Disconnect the air lines from the high and low
ports, and place a voltmeter across the OUT and
GND terminals on the DPT-2015. If the output is
not between 0.4 and 0.6 volts with power applied
to the DPT-2015 in the vertical position, the
transmitter is defective and should be replaced.
Note:
Voltage readings may vary by 0.1 volt if the
transmitter is in the horizontal position.
Repairs and Replacement
Field repairs must not be made. For a replacement
product or an accessory, refer to the
M9106-AGx-2N0x
Series Electric Non-Spring Return Actuators Product
Bulletin (LIT-2681126).
