Local / Remote switch-over of the Control Station

The control station can be switched over either by operating the OS (REMON_OP), or by linkable
input REM_L. If REM_SEL=TRUE, input REM_L is active, otherwise control input REMON_OP is
active. The required operator enabling signal QLOCOP is set by REM_SEL and enable
signal LOCOP_EN.
The active control station is output through QREMOTE (1=REMOTE, 0=LOCAL).

Control Function DIR, SOFT, STAR, REV, POL, DAHL
• When LOCK is set, the motor is switched off directly or cannot be switched on.
• LOCK_ON switches the motor on or prevents it from being switched off.
• LOCK_OPT is used to define the option selected for LOCK_ON = 1 (forward / reverse; fast /
slow).
Note
LOCK_OPT is not active for control functions DIR, SOFT, and STAR.
LOCK has higher priority than settings made with LOCK_ON.
Control Function VALVE, POS
• With LOCK set, the solenoid valve or positioner runs in the position defined by safety
position SS_POS.
• VL_OPEN causes selection of OPEN position and VL_CLOSE causes selection of CLOSED
position.
• VL_HOLD is only active in the POS control function and causes the positioner to stop at its
current position.
