Page 4: Introduction
This unit may be equipped with either two 3-wire switches or two 2-wire inductive sensors. Warnings WARNING: The aluminum housing Model EaziCal II Ex ia is at potential risk of ignition by impact or friction therefore, care must be taken into account during installation to avoid this problem. -
Page 5: Description
Mechanical, proximity & inductive proximity type. Principles of Operation The EaziCal II utilizes two keys for auto calibration and two keys for settings. This controls both Positioner and Position Transmitter with local LCD in conjunction with the Diagnostic / Fault LED. -
Page 6: Special Features
20mA with 4mA being 0% open and 20mA being 100% open. If the main section of the EaziCal II fails and so ceases to provide position updates to the Transmitter or the position sensor fails on the main section, so that the current valve position is unknown, the Transmitter will put out a current of 3.5mA or 21.5mA... -

Page 10: Calibration
Figure 3 Standard Flow Manifold Figure 4 High Flow Manifold Calibration There are 3 auto calibrate modes (all modes auto calibrate the Transmitter) o Auto Calibration for 4mA to 20mA. o Calibration for Low current calibration other than 4mA. o Calibration for High current calibration other than 20mA. 4.3.1 Auto Calibration for 4mA to 20mA operation This is a two Key auto calibration that defines 4mA for the valve being fully closed and 20mA for valve being fully open. - Page 11 4.3.2 Auto Calibration for Low current Calibration other than 4mA (Split Range) The Low calibration refers to the input current value that drives the valve into the fail position. The Transmitter Function is being automatically calibrated during this procedure. First follow the procedure for the Auto Calibration Next set loop current to the desired value.
- Page 12 To enter Manual Calibration, Press the Key until MAN CAL is shown on the display will show FWGN xx. Repeatedly pressing the switch will cycle through what can be changed. FWGN xx RVGN xx DR ENABL or DR DISAB based upon what is set ZERO xx SPAN xx DIR ACTG or REV ACTG based upon what is set...
- Page 13 4.4.5 Span Position (SPAN XX) - Adjusts the electronic stop away from (increasing values) or towards (decreasing values) from the physical open position. 0 being nominally the position of the hard stop Span Zero and 100 about 15 degrees away from it Pressing DOWN Key reduces the span position of the valve away from the hard stop Pressing UP Key moves the span position closer to the hard stop.
- Page 14 4.4.10 Cancelling Calibration When the LCD displays “AUTO CAL” and you do not want to perform this operation. Do nothing. Within 15 seconds the function displayed is canceled and the LCD display reverts back to opening percentage “xx %” If starting an Auto Calibration by mistake. Wait 5 seconds and press again.
- Page 15 Before stroking the actuator, please ensure that the process is safe to do so and that all hands are kept away from the moving shaft / cams. Stroke the actuator to the opposite end of travel. Set the top EasiFix self-locking cam by pushing down and turning the EasiFix self-locking cam until the switch is activated.

Page 17: Maintenance And Repair
Maintenance and Repair The positioner’s onboard filter should be replaced regularly or whenever it gets clogged. See diagram below for location of the filter. Note: the following instructions are for Standard Flow. For High Flow please contact the factory. Important: The positioner’s onboard filter is not a substitute for normal instrument air preparation. -
