Scan Function (
SCan
)
The
Scan
menu is used to program the PV scan mode and the scanner’s behavior on alarm condition. The
operator is able to scan automatically based on a time parameter, or scan manually with front panel keys
or digital inputs. The operator is also able to set the scanner to stop on alarm or continue scanning on
alarm. To resume scanning the operator must press the Next or Previous button. Please follow the menu
below for details. In the Stop on Alarm mode, the scanner will go to the alarmed PV and remain there until
the operator manually advances to the next PV or returns to the previous PV. If a new alarm is detected
the process is repeated. The scanner ignores old alarms.
Control Menu (
Contrl
)
The
Control
menu is used to control the 4-20 mA analog output and the relays manually, ignoring the input.
Each relay and analog output can be programmed independently for manual control. Selecting automatic
control sets all relays and analog output for automatic operation.
