Appendix A
Digital Signalling Mode (solid-state output)
Controls the solid-state switch response to level settings, and allows you to set the
switch to contact open or contact closed. The settings are relative to a covered probe,
and the criteria are set in Upper and Lower Threshold settings (see pages 75 and 76,.
menus 15 and 16). With contact closed, the switch is on: with contact open the switch is
off.
While a button is pressed, the LCD displays S: cc
1
(contact closed) or S: co (contact
open). When the button is released an equal sign (=) indicating status replaces the colon,
and the reading depends on the status of the probe
2
.
Example: S = cc is selected (contact closed with a covered probe)
• If the probe is uncovered when the button is released, the display changes from
S: cc to S = co.
• If the probe is covered when the buttons are released, the display changes to
S = cc.
• If you press either button briefly, the LCD displays the current setting, in this
case, S: cc.
Notes:
•
Factory setting FSH links menus 17 and 18, and sets them to enable digital fault
signalling. (In Free Programming Mode, available at menu 1E, all menu items are
independent.)
•
Menu 18 has precedence over menu 17.
1.
A colon at the extreme left of the display appears while the button is pressed to
indicate when a setting is accepted, for example : S: cc.
2.
If digital fault signalling is enabled at menu 18, it takes precedence, and no equal sign
will appear in the display for menu 17 if the device is responding to a fault.
