EP-311/313 ELECTROPNEUMATIC TRANSDUCER INSTALLATION INSTRUCTIONS
Figure 3 - Terminal Locations on EP-311/313
Installation Adjustments: The EP-311/313 is supplied from the factory
set for 4-20 mA. To change the input configuration, adjust the Dip switch
settings as illustrated in Figure 4 (below).
CHECKOUT
1. Verify that the unit is mounted in the current position.
2. Verify appropriate supply voltage.
3. Verify appropriate input configuration.
TRANSDUCER OPERATION
This is a rough functional check only.
1. Adjust the input signal to obtain maximum output pressure for
appropriate range.
2. Output should be 15 or 20 PSIG.
3. Adjust the input signal to obtain minimum output pressure.
4. Output should be 0 or 3 PSIG.
CALIBRATION
All units are factory calibrated to meet or exceed published specifications.
If field adjustment is necessary, follow the instructions below.
1. Connect air to main port.
2. Connect branch port to an accurate gauge with a minimum 6 to 10 ft.
(1.8 to 3.0m) of tubing.
CAUTION: NEVER connect 120 VAC to these transducers!
3. Connect terminals + and - to the appropriate power source for this unit.
The EP-311/313 can accept either 24 VAC or 24 VDC supply voltage.
The maximum supply voltage should not exceed 30 VAC/VDC.
4. Apply low input signal to terminals - and I (0 VDC or 4 mA).
5. Adjust Z to obtain desired output low pressure.
6. Apply high input signal to terminals - and I (5/10 VDC or 20 mA).
7. Adjust S to obtain desired output high pressure.
8. Repeat Steps 4-7 until the unit is completely calibrated.
MAINTENANCE / FIELD REPAIR
Regular maintenance of the total system is recommended to assure sustained
optimum performance. No field repair is possible. Replace suspect devices
with a functional unit.
WARRANTY
See Data Sheet for additional information.
