17.3 EMERGENCY-OPEN and EMERGENCY-CLOSE
signal (option)
(5th digit in wiring diagram MSP ... C, D or P)
When an EMERGENCY run command is given the actuator operates the
valve to the predetermined
end position (effective in all three selector switch positions: LOCAL, OFF,
REMOTE).
.
The input at terminal X
K
1 (refer to wiring diagram) must be connected to a
NC-contact (closed circuit principle) at + 24 V DC.
.
If EMERGENCY-OPEN or EMERGENCY-CLOSE signal is generally not
desired:
Disconnect links B1 (for EMERGENCY-CLOSE) and B2 (for EMER-
GENCY-OPEN).
18.
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 any part of the travel.
.
The timer is installed in the AUMA MATIC instead of the interface board
(figure L, page 20).
