1.3 Description
The Eazi al II is a 4-20mA electro-pneumatic valve positioner/controller. Position
measuring is performed by off-set, shaft driven, state of the art Hall Effect Sensor. The
positioner comes standard with 4-20mA feedback transmitter. In addition there are
options for feedback limit switches, Mechanical, proximity & inductive proximity type.
1.4 Principles of Operation
The Eazi al II utilizes two keys for auto calibration and two keys for settings. This controls
both Positioner and Position Transmitter with local L D in conjunction with the
Diagnostic / Fault LED.
The Eazi al II uses Hall Effect position sensing with ‘off axis’ detection to allow a through
shaft for the top mounted Westlock Beacon.

Manual tuning
oSet Drop Off on/off
oSet Gain, Zero and Span positions
oL D displays loop current, valve position.
Integrated Transmitter
The transmitter operates from the same sensor input as the main unit, but is powered by
a separate loop. It shows the current position of the valve by sinking between 4mA and
20mA with 4mA being 0% open and 20mA being 100% open.
If the main section of the Eazi al 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
(selectable), to indicate this failure. This “fail” current will be put out within 200ms of the
actual failure. If the main unit detects an error >10% of position, the transmitter will
output fault current and the Fault LED starts blinking.
Open/close Limit Switches
These are optional SPDT Mechanical, SPDT T-Switch or NAMUR Inductive proximity
sensors.
Note : For general purpose Eazical II products ONLY, other Inductive proximity sensors
are available. See wiring diagrams 11 & 12.

4.3 Calibration
There are 3 auto calibrate modes (all modes auto calibrate the Transmitter)
oAuto alibration for 4mA to 20mA.
oalibration for Low current calibration other than 4mA.
oalibration 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. The Transmitter Function is being automatically
calibrated during this procedure.
Time for the first move in calibration will be set at a maximum of 30 seconds for REG CAL
and all subsequent time outs are keyed off the time it takes to go from closed to open, to
create much shorter subsequent time outs for smaller valves. The initial 2 minute time
out can be lengthened in the Manual alibration routine Long CAL.
Press
SEL
Key until the Display shows “AUTO AL” then press Key.
Auto calibration will occur for 4mA low current and 20mA high current.
The display will show:
AUTO AL
STARTED
LOW AL The valve is closed and the closed position recorded.
HIGH AL The valve is opened and the open position recorded.
GAIN The valves best gain setting is found.
ALIBRATION SU ESS

6 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. Supply air to the positioner should conform to ISA Standard S7.3 - Quality for
Instrument Air.
Important: The filter’s original color is chalk white. If the filter is discolored, its replacement
should be performed more often. A discolored filter may also indicate the need for an
evaluation of the air-supply quality. A filter/regulator with a 5 micron or better element,
just prior to the positioner, is therefore recommended.
