Page 9 Safety instructions and measures − Servicing explosion-protected devices If a part of the device on which the explosion protection is based needs to be serviced, the device must not be put back into operation until a qualified inspector has assessed it according to explosion protection requirements, has issued an inspection certificate, or given the device a mark of conformity. Inspection by a qualified inspector is not required if the manufacturer performed a routine test on the device before putting it back into op- eration.

If this is not the case, change the slide switch position and re-initialize the positioner.

Exit Code 1 by pressing the rotary pushbutton ( The permissible range has been exceeded when the displayed angle is more than 30° and the outer right or left bar element blinks. The positioner goes to the fail-safe position (SAFE). After canceling the fail-safe position (SAFE) (see section 7.12.2) it is absolutely essential that you check the lever and pin position as described in section 5.

Page 104 Operating the positioner 7.6.1 MAX – Initialization based on maximum range The positioner determines travel/angle of rotation of the closing member from the CLOSED position to the opposite travel stop and adopts this travel/angle of rotation as the operating range from 0 to 100 %.

Page 105 Operating the positioner 7.6.2 NOM – Initialization based on nominal range The calibrated sensor allows the exact valve travel to be measured very accurately. During initialization, the positioner checks whether the control valve can move through the indicated nominal range (travel or angle) without collision. If this is the case, the indicated nominal range is adopted with the limits of travel/angle range start (Code 8) and travel/angle range end (Code 9) as the operating range.

Page 108 Operating the positioner 7.6.4 MAN2 – Initialization based on manually selected end po- sitions Before starting initialization, move the control valve manually to the end positions. The posi- tioner calculates the travel/angle difference from the positions that the valve moved to and adopts it as the operating range with limits of lower travel/angle range value (Code 8) and upper travel/angle range value (Code 9). Note This initialization mode can only be started when the valve position differs in the end posi- tions and the positioner has not yet been initialized.

Page 119 Operating the positioner 7.9 Adjusting inductive limit switch The positioner version with an inductive limit switch has an adjustable tag (1) mounted on the axis of rotation, which operates the proximity switch (3). For operation of the inductive limit switch, the corresponding switching amplifier (see sec- tion 5.16.2) must be connected to the output circuit. When the tag (1) is located in the inductive field of the switch, the switch assumes a high re- sistance. When it moves outside the field, the switch assumes a low resistance. Normally, the limit switch is adjusted in such a way that it will provide a signal in both end positions of the valve.
Page 120 Operating the positioner For CLOSED position: 1. Initialize the positioner. 2. Move the valve to 5 % in the MAN mode (see display). 3. Adjust the tag at the yellow adjustment screw (2) until the tag enters or leaves the field and the switching amplifier responds. You can measure the switching voltage as an indicator. Contact function: − Tag leaving the field > contact is closed. − Tag entering the field > contact is opened. For OPEN position: Initialize the positioner. Move the valve to 95 % in the MAN mode (see display). Adjust the tag (1) at the yellow adjustment screw (2) until the tag enters or leaves the field of the proximity switch (3).
