Quick Guide .....(English)

These instructions are to be used as a guide for quick start-up. For more detailed information please refer to the standard documents "Master Instructions" and "Product Specification Sheet". These can be found on our Website.

1 MOUNTING TO LINEAR ACTUATORS

Single-acting diaphragm actuators

Check whether the actuator is in the safety position required by the process. (Does the actuator open or close with spring force?) The mounting side is selected from the table below in accordance with the direction of action and the required direction of movement of the spindle for an increasing input signal.

Actuator closes with spring force	Changeover plate setting	Actuator opens with spring force	Changeover plate setting

The arrow indicates the direction of movement of the spindle at increasing input signal.

The direction of action of the input signal can be set on the changeover plate 13 :

N = Normal direction of action (increasing input signal produces increasing control pressure to the actuator)

U = Reverse direction of action (increasing input signal produces decreasing control pressure to the actuator)

Double-acting diaphragm actuators

For double-acting positioners the changeover plate 13 always stays in the "N" setting. The assignment of the input signal to the direction of movement of the actuator spindle is determined by the selection of the mounting side of the positioner and the piping of the positioner outputs to the actuator:

Ensure that the feedback lever 11 is horizontal at 50 % stroke.

Fasten housing cover in such a way that air vent of attached device faces downwards (see Mark 'M').

2 MOUNTING TO ROTARY ACTUATORS

a) Remove the transparent cover plate from the housing of the attachment kit.
b) Mount the housing of the attachment kit on rotary actuator or armature; use mounting hardware supplied by the actuator manufacturer if necessary.
c) Move actuator into the desired starting position (rotation angle = 0°).
d) Mount cam 24 in accordance with the direction of rotation of the actuator.

The linear cam is fastened to the actuator drive shaft in such a manner that the distance x between the inside of the housing and the came amounts 2 mm, whereas in case of equal percentage cam the dimension x is approx. 17.5 mm.

In case of inverse equal percentage cam the dimension x is approx. 18 mm.

When employing equal percentage and the inverse equal percentage cams, the range spring (yellow) EW420493013 must be installed in the positioner.

e) Fasten feedback lever 30 for the rotary actuator onto shaft 15 of positioner.
f) Mount positioner on housing of attachment kit. Attach spring 31 to feedback lever 30 and cam follower 32 against cam.

Screw positioner to housing of attachment kit. With the linear cam and the inverse equal percentage cam check whether mark 33 points to the center of the cam follower 32; adjust if necessary.

With the equal percentage cam check whether the cam follower lies directly ahead of the start of the cam lobe; adjust if necessary.

g) Final mounting of feedback lever on shaft of positioner is performed at a stroke of 0 %, i.e. a rotation angle of 0°. First loosen 5 mm A/F Allen screw of feedback lever 30 through hole 34, then press stroke factor lever 17 against stop screw 18 (see page 5) and tighten Allen screw firmly.

31 32 + - Analog output 4 to 20 mA 2 wire system Supply voltage DC 11 to 48 V S1 S2

5 SETTINGS AND START UP

5.1 Setting of zero point and stroke on the positioner

(see page 6 for the reference of the number)

Before starting with the set-up push the flapper lever 40 several times alternately to the left and right in order to align the flappers correctly.

a) Set the minimum value of the input signal w (start of stroke).

b) Turn zero screw 41 until actuator just begins to move from its end position.

c) Set maximum value of the input signal w (end of stroke).

d) Turn the stroke factor screw 42 until actuator precisely reaches its end position:

Right turn: decrease of travel

Left turn: increase of travel

Repeat the operations (a to d) 2 or 3 times in order to insure an accurate positioning.

Hubfaktor 41 42

Note:

Changes of the gain will influence the settings of zero and span.

If the stroke cannot be adjusted with the installed spring, a suitable spring can be determined with the table on page 5.

5.2 Adapting to air supply

The positioner is adjusted in the factory for an air supply pressure of 3 bar. If the device will be used with a different air supply pressure, the gain has to be adjusted with screw 44. For a higher air supply pressure the screw should be moved clockwise (for 6 bar to the end).

5.3 Setting the damping

The air output capacity of the positioner can be reduced by means of the damping throttle 46. Double-acting positioners are equipped with a damping throttle 47 for correcting the variable y1 and a damping throttle 48 for correcting the variable y2. In its normal setting the damping throttle is approximately flush with the amplifier housing.

The air output capacity is reduced by a factor of approximately 2.5 when the damping throttle is turned completely.

5.4 Setting and Start Up of position transmitter 4-20 mA

Attachment and start-up of the unit to the actuator must be performed according MI EVE0102 A or MI EVE0101 A. At 50% stroke, the control lever must be horizontal.

The electronic connection of the position transmitter must be assured. Both LEDs are then light up.

Adjusting the start of the measuring range (4 mA)

a) Move the actuator to the starting position.

b) Press push button S1 „Config Output 4 mA“ longer than 2 seconds. During this time LED 1 lights up. After 2 seconds both LEDs are light up again, the value for 4 mA is stored.

Adjusting the end of the measuring range (20 mA)

a) Move the actuator to the end position.

b) Press push button S2 „Config Output 20 mA“ longer than 2 seconds. During this time LED 2 lights up. After 2 seconds both LEDs are light up again, the value for 20 mA is stored.

Random adjustment of the current values at the end points

a) Move the actuator to the end position, where you want to adjust the current.

b) Press both buttons simultaneously for about 2 seconds. Then both LEDs are alternating flashing in a slow frequency.

c) With push button S1 „Config Output 4 mA“ the output current value can be decreased and with push button S2 „Config Output 20 mA“ the output current value can be increased. Pressing the buttons for a short moment results in a small change and pressing the button for a longer time results in a fast mode for a bigger change. The value of the current can be freely decreased approximately between 3.3 and increased up to 22.5 mA.

d) Without any additional manipulations of the push buttons the new value is automatically saved. After a few seconds, the device returns into the normal operating mode, indicated by both LEDs that then light up again.

Trouble shooting of the position transmitter

The components of the position transmitter are under constant surveillance by the installed micro controller. Errors are detected and indicated when both LEDs are off or both LEDs are parallel flashing at a fast frequency.

In the event of a fatal error, e.g. potentiometer not connected, an output current of 24 mA will be shown in addition to the error indication given by the LEDs (fast flashing).

In this case check the following:

a) if the potentiometer is correctly connected to the electronic board.

b) if the potentiometer is within its working span.

When both LEDs are off, the supply voltage should be checked (minimum tension, polarity).

5.5 Spring range

Five different springs for the travel-ranges are available for matching to the stroke and input signal range. In the following table the stroke range is given for a normal application (4-20 mA and with our standard feedback lever).

Spring range Stroke range		in mm	Remarks
