AUMA SAM Ex 07.1 - Function of the Diagnosis Leds (Timer); 17 Timer (Option)

Example:
Two actuators are to be operated in Split Range version. Actuator 1 must be
in position CLOSED with a nominal value signal E1 of 0 mA, and in position
OPEN with a signal of 10 mA.
Actuator 2 must be in position CLOSED with a nominal value signal of
10 mA, and in position OPEN with a signal of 20 mA.
.
Positioner actuator 1:
Supply E1 = 0 mA, set with P5 = 0 V at M3,
supply E1 = 10 mA, set with P6 = 5V at M9.
.
Positioner actuator 2:
Supply E1 = 10 mA, set with P5 = 2,5 V at M3,
supply E1 = 20 mA, set with P6 = 5 V at M9.
.
Perform adjustments and settings for E2 etc. Afterwards the nominal value
E1 can be transmitted through both actuators (can be connected in
series). When operating within range E1 = 0 - 10 mA the actuator 1
moves, actuator 2 remains in end position CLOSED. When operating
within range E1 = 10 - 20 mA the actuator 2 moves, actuator 1 remains in
end position OPEN.
17. Timer (option) With the timer board the operating time can be increased for the entire or
any portion of the valve travel.
Example:
In order to avoid water hammer in long pipelines, stepping mode can be
chosen for each part of the travel.
.
The timer is installed in the AUMA MATIC Ex instead of the interface
board (figure P, page 19).
.
Electronic timer is not possible in combination with positioner.
