4.13.9 Change Clock
CHANGE CLOCK allows the user to select the real time clock settings. Select NO if you do not wish to set the clock and
the menus will return to CHANGE HART. Select YES to enable clock and set YEAR, MONTH, DAY, HOUR, MINUTE, and
SECOND values. SAVE CLOCK allows the clock settings to be saved. The clock is non-volatile if power is lost or the unit is
reset, the clock must be set again. If the clock is enabled, the LCD will display “SET CLOCK” after a power cycle/reset. If the
clock is not enabled, the LCD will not display “SET CLOCK”. The clock may also be set and read from the network via HART
commands 89 and 90. If the clock is not set, the HART board will keep a running counter in place of the clock.
4.14 Status and Alarm Contacts
The status and alarm contacts permit wiring to existing contacts for visibility of operation or fault conditions. (See wiring
diagram for contact ratings.)
The status contacts (S) and optional alarm contacts (R) may be configured to have any one of the following functions:
• “CLOSING” – valve closing
• “OPENING” – valve opening
• “STOPPED” – valve stopped in mid-travel
• “VALVE MOVING” – either direction
• “LOCAL SELECTED” – red selector knob in “LOCAL”
• “MOTOR OVERTEMP” – thermistor range exceeded
• “OVERTORQUE” – torque exceeded in mid-travel
• “MANUAL OVERRIDE” – actuator moved by handwheel
• “VALVE JAMMED” – valve can’t move
• “CLOSE TORQUE SW” – torque switch trip at “CLOSED”
• “OPEN TORQUE SW” – torque switch trip at “OPEN”
• “LOCAL STOP/OFF” – red selector knob at “STOP Selected”
• “LOST PHASE” – one or more of three phases lost
• “ESD SIGNAL” – signal active
• “CLOSE INHIBIT” – close inhibit signal active
• “OPEN INHIBIT” – open inhibit signal active
• “ANALOG IP LOST” – 4-20 mA not present
• “REMOTE SELECTED” – red selector in “REMOTE”
• “LIMIGARD ACTIVE” – (future—LimiGard™ functionality is not affected)
• “HARDWARE FAILURE” – indication
• “NETWORK CONTROLLED” – permits relay control via DDC, FF, or other network driver
• “CLOSE” – valve closed “(0% OPEN)”
• “OPEN” – valve open “(100% OPEN)”
• “MID-TRAVEL” – valve position, 1-99% open
• “CSE CONTROL” – CSE station in LOCAL or STOP and controls actuator
• “PS ACTIVE”, “PS PASSED”, “PS FAILED TARGET”, “PS FAILED RETURN”
• “PS” – Partial Stroke, activated if PS is configured
