NOTE: Do not replace the One Series display module or pressure
sensor. Swapping these amongst devices will cause a mis-match
between the stored sensor calibration data and the pressure sensor.
For proper operation, the display module serial number must always
match the serial number inside the enclosure (See Figure 12).
These serial numbers must match for proper operation.
DISPLAY MODULE CALIBRATION
ACCEPTABLE SUPPLY VOLTAGES AND LOADS FOR 1XSWLL AND 1XSWHL
The graphs below provide a range of acceptable power supply voltages (in Volts) and series loads (in Ohms). This is useful when the One Series
is connected to non-standard PLC and DCS inputs or is connected in series with a relay or solenoid coil.
NOTE: If you need assistance with determining the compatibility of the One Series with your PLC, DCS, or relay, we can help. Please have the manu-
facturer's model number ready when you call us. In rare cases, when the series resistor value is too large and falls out of the Acceptable Range,
placing another resistor across the input will allow it to work. Please call +1 (617) 923-6977 (Inside Sales) for assistance.
