4.1.9 MANUAL / AUTOMATIC Operation
Manual / Automatic
The operating mode can be switched either by operating AUTON_OP at the OS, or by linkable
input AUT_L. If LIOP_SEL=TRUE, input AUT_L is active, otherwise control input AUTON_OP is
active. The required operator enabling signal QMANOP and QAUTOP are set depending
on LIOP_SEL and enable signals MANOP_EN and AUTOP_EN. The active operating mode is
output on QMAN_AUT (1=AUTO, 0=MANUAL).
Automatic
In automatic mode, the control commands are set by a program through linked inputs.
If AUTO_M=TRUE, the commands are set through inputs AUTO_ON1, AUTO_OFF,
and AUTO_ON2. Otherwise, inputs AUTO_ON and AUTO_OPT are active.
Manual
In manual mode, the control commands are set by the operator either at the OS or through
linked inputs. The linked inputs are L_ON1, L_OFF and L_ON2. Control from the OS is performed
through inputs ON1_OP, OFF_OP, ON2_OP. For control through the OS, operator enabling
signals QON1OP, QOFFOP, and QON2OP are required. These signals are set depending on control
function SIMO_FCT, the active operating mode, and enable signals ON1OP_EN, OFFOP_EN,
ON2OP_EN.
4.1.10 MANUAL-LINKED / MANUAL-OPERATOR
In manual operation, the control commands are set by the operator either at the OS or through
linked inputs. It is possible to switch between these two options, again either through the OS or
through a linkable input. If MAN_SEL=TRUE, the setting of linkable input MAN_L is active,
otherwise control input MANON_OP is active.
The required operator enabling signal QMANLOP is set depending on MAN_SEL and enable
signal MANLOPEN.
The active setting is output through QMAN_MOP (1=MANUAL-LINKED; 0=MANUAL-OPERATOR).
