The analyzer may be equipped with up to four electrome-
chanical relays (A, B, C, and D). Each relay can be set to
function as a CONTROL, ALARM or STATUS relay. For
details on each relay function, see subsection “SET
FUNCTION Mode.”
During calibration, CONTROL and ALARM relays can be
held, transferred to preset on/off states or remain active.
During normal measurement operation, CONTROL and
ALARM relays can be held at their present on/off states:
•
For up to 30 minutes by selecting the “HOLD
OUTPUTS” line in the TEST/MAINT menu and
pressing the
ENTER key
.
•
For an indefinite period by locally or remotely
connecting both TTL input Terminals 9 and 10 on TB1.
If a TEST/MAIN hold is applied in addition to a TTL hold,
both “holds” must be removed before CONTROL and
ALARM relays return to active status. If the relays are set to
XFER or ACTIVE during calibration, they remain in that cor-
responding on/off state regardless of the connection status
at the TTL input terminals.
These instructions configure Relay A. Configure other
relays in the same way using their respective menu
screens.
