Safety functions
Monitoring function
SARV 16.2 Control unit: electronic (MWG)
Standard:
Selectable type of seating, limit or torque seating for end position OPEN and end po-
sition CLOSED
Torque by-pass: Adjustable duration (with adjustable peak torque during start-up time)
Start and end of stepping mode as well as ON and OFF times can be set individually
for directions OPEN and CLOSE, 1 to 1,800 seconds
Operation profile with any 8 intermediate positions: Position can be set between 0 and
100 %, reaction and signal behaviour programmable
Velocity profile with up to 10 ranges, velocity can be individually adjusted for positions
OPEN and CLOSED for each range
Running indication blinking: can be set
Speed/operating time source can be selected (REMOTE, LOCAL)
4 internal nominal speeds or operating times can be programmed (and selected in
LOCAL)
Nominal speed source can be selected for REMOTE (binary, analogue, fieldbus)
Soft start, soft stop with velocity reduction (adjustable)
Positioner:
-
Position setpoint via fieldbus interface
-
Programmable behaviour on loss of signal
-
Automatic adaptation of dead band (adaptive behaviour selectable)
-
Change-over between OPEN-CLOSE control and setpoint control via fieldbus
-
Modulating duty with proportional operation (2 %
-
Positioning accuracy <0.2 % (SAV/SARV .2 only)
Options:
PID process controller: with adaptive positioner, via 0/4
process setpoint and actual process value
Multiport valve: Up to 16 positions, signals (pulse or edge) (SAV/SARV .2 only)
Lift Plug Valve: In combination with multiport valve (SAV/SARV. 2 only)
Automatic deblocking: Up to 5 operation trials, travel time in opposite direction can be
set
Static and dynamic torque recording for both rotation directions with torque measure-
ment flange as additional accessory
Standard:
EMERGENCY operation (programmable behaviour)
-
Via additional input (option, low active) or via fieldbus interface
-
Reaction can be selected: STOP, run to end position (OPEN, CLOSED) or inter-
mediate position at defined speed
-
Torque monitoring can be by-passed during EMERGENCY operation
-
Thermal protection can be by-passed during EMERGENCY operation (only in
combination with thermoswitch within actuator, not with PTC thermistor).
Options:
Enabling local controls via Enable LOCAL digital input: Thus, actuator operation can
be are or disabled via push buttons on local controls.
Interlock for main/by-pass valve: Enabling the operation commands OPEN or CLOSE
via two digital inputs
EMERGENCY Stop push button (latching): Interrupts electrical operation, irrespective
of the selector switch position
PVST (Partial Valve Stroke Test): programmable to check the function of both actuator
and actuator controls: Direction, stroke, operation time, reversing time
Valve overload protection: Adjustable, results in switching off and generates fault signal
Motor temperature monitoring (thermal monitoring): Results in switching off and generates fault
signal
Monitoring the heater within actuator: Generates warning signal
Monitoring of permissible on-time and number of starts: Adjustable, generates warning signal
Operating time monitoring: Adjustable, generates warning signal
Phase failure monitoring: Results in switching off and generates fault signal
