SP7-10, SP7-11, SP7-12 and SP7-20, SP7-21, SP7-22 Parameterization
3.10.2 MAX_VR – Operating range max.
Normally, the operating range is determined automatically during Autoadjust. A partial run of automatic adjustment that is limited to the
controller data (STANDARD, see parameter ADJ_MODE) or valves and fittings without end stops, however, requires manual adjustment
of the operating range.
CAUTION
Risk of injury!
After manual adjustment of the end positions, it is essential to limit the operating range to > 0.1 and < 99.9 under
MIN_RGE and MAX_RGE. Otherwise, the valves and fittings may be driven at full speed to an end position.
- Do not reach into the adjustment mechanism.
The range between high and low limit value must be at least 10% of the full range. Otherwise, the message VR< 10 % is displayed.
NOTE
Use as large are range as possible. This parameter is not active when the safe position is active . The display
then shows the message FAIL POS.
Use MAX_VR to determine the upper limit of the operating range.
ARROW UP or ARROW DOWN Press in order to travel to desired position.
ENTER
Press and hold until the countdown has completed (MIN_SET. The position is saved as the
minimum limit value
ENTER Press briefly. The set lmit value is displayed for 2 seconds (MIN_SAVE).
3.10.3 ACTUATOR – Actuator type
With this parameter you can configure the positioner for operation on a linear actuator (sensor range ±30°) or on a part-turn actuator
(sensor range ±45°). No mechanical modifications to the positioner are required.
NOTE
After changing the actuator type , it is recommended that you run Auto Adjust to prevent linearity errors.
