8.2.2.5. Description of the block parameters of the transducer
• Suitable for solenoid valve application;
• Two proximity switches for each solenoid outlet;
• The input signals indicate the ON/OFF status of the valve.
Parameter Description
VALVE_MAN Name of the valve manufacturer
ACTUATOR_MAN Name of the actuator manufacturer
VALVE_SER_NUM Serial number of the valve belonging to the device
ACTUATOR_SER_NUM Serial number of the actuator belonging to the device
VALVE_ID Identification of the valve (valve type)
ACTUATOR_ID Identification of the actuator (actuator type)
ACTUATOR_ACTION Safety position if actuator or valve has power failure:
0 not initialized
1 open
2 closed
TRAVEL_COUNT Number of cycles from “open” to “closed” and from “closed” to “open”. The number
range of the TRAVEL_COUNT exceeds the storage capability of the EEPROM
TRAVEL_COUNT_LIM
Limit of the parameter TRAVEL_COUNT; if 0, TRAVEL_COUNT_LIM is not pro-
cessed. If the LIMIT values are exceeded, the corresponding bit in the parameter
CHECK_BACK is set.
TRAVEL_TIME_CLOSE_
OPEN Set-point value for the time in seconds between the change of status from CLOSED
to OPEN; if 0, the time is not processed. If the time is exceeded, the corresponding
bit in the parameter CHECK_BACK is set. Times less than 0.5 seconds cannot be
monitored.
TRAVEL_TIME_OPEN_
CLOSE Set-point value for the time in seconds between the change of status from OPEN to
CLOSED; if 0, the time is not processed. If the time is exceeded, the corresponding
bit in the parameter CHECK_BACK is set. Times less than 0.5 seconds cannot be
monitored.
TRAVEL_TIME_CLOSE_
OPEN_TOL Maximum time difference between TRAVEL_TIME_CLOSE_OPEN and the current
switching time
TRAVEL_TIME_OPEN_
CLOSE_TOL Maximum time difference between TRAVEL_TIME_OPEN_CLOSE and the current
switching time
SELF_CALIB_CMD Device-specific calibration
- - - - - - x y
y = 0 de-energized active
y = 1 energized active
x = 0 Sensor 1 displays “Valve open”
x = 1 Sensor 1 displays “Valve closed”
SELF_CALIB_STATUS
Result or status of the device-specific calibration (depending on manufacturer)
0 Standard setting
