Pneumaticconnection
12.1 Connection of external position
sensors for type EP 501 L
→
Connect 4 – 20 mA path sensor to the terminals 1 - 4 of the
type EP 501 L (see chapter „14.5.1 Terminal assignments of the
process actual value input").
Internal supply of the path sensor by Type EP 501 L:
→ Connection according to input type "4 – 20 mA - internally
supplied".
Separate supply of the path sensor:
→ Connection according to input type "4 – 20 mA - externally
supplied".
→
Attach remote sensor on the actuator.
The correct procedure is described in the instructions for the
path sensor.
→
Connect compressed air to the Type EP 501 L.
→
Connect Type EP 501 L pneumatically to the actuator.
→
Switch on Type EP 501 L operating voltage.
→
To obtain the best possible control precision, adjust the path
sensor so that path to be measured corresponds to the signal
range 4 – 20 mA (only if the path sensor includes this function).
→
In the ADD.FUNCTION menu activate the POS.SENSOR
function. Then select POS.SENSOR in the main menu and set
ANALOG.
The procedure is described in the operating instructions for the
device in the chapter "Starting up and operation of the process
