MODULE #6 - PROGRAM ALARM/SETPOINT

If the alarm option is installed, this module is used to configure the operation of the alarms to a variety of combinations. The programmable options are HI/LO acting, auto/manual reset (latching), tracking, assignment to input or integrator/totalizer, display alarms, alarm values and hysteresis (deadband) values.

ALARM TRACKING

With alarm tracking, whenever alarm #2 is changed, alarm #1 will also change so that the offset between alarm #2 and alarm #1 remains the same. This is useful for hierarchical setpoints (pre-alarm and alarm) when one change applies to both alarm values. When programming from the front panel, tracking only occurs when PGM. DIS. is low (front panel lock-out mode, alarm #1 will not appear). Tracking will always occur if alarm #2 is modified via serial communications independent of PGM. DIS.

“trAc” < > “yES” or “NO”

DISPLAY ALARMS

If display alarms are desired, a message will flash on the display every 5-10 secs when an alarm activates. For alarm 1, the message will flash “AL1 ON” and alarm 2 will flash “AL2 ON”. This warns an operator of an alarm condition. The message will stop when the unit is no longer in an alarm condition.

“dISP” < > “yES” or “NO”

AUTO OR MANUAL RESET FOR ALARM #1

The reset action of alarm #1 may be programmed to reset automatically (unlatched) or be programmed to require a manual reset (latched), through either a remote input (E1-CON or optional E2-CON)or through the front panel. Latched alarms are usually used when an operator is required to take some action for the alarm condition.

“LAtC-1” < > “yES” or “NO”

ALARM #1 ASSIGNMENT TO INPUT OR

INTEGRATOR/TOTALIZER

Alarm #1 may be programmed to activate on either the input or the integrator/totalizer value. If the integrator/totalizer option is not installed, this step defaults to the input.

“ASN-1” < > “INPUt” or “totAL”

PROGRAM VALUE FOR ALARM #1

The range of the alarm value is -999 to 9,999 for the input display and -99999 to 999999 for the totalizer option display.

“AL-1” < > “-999” to “9999”

PROGRAM HYSTERESIS VALUE FOR ALARM #1 (Cannot be programmed if alarm latch is programmed)

The hysteresis (deadband) value for alarm #1 may be programmed from 1 to 9,999 for the input and 1 to 999999 for the totalizer option. The value is either added to or subtracted from the alarm value depending on whether the alarm is high or low acting. (See “alarm” section for operation.)

“HyS-1” < > “1” to “9999”

ALARM #1 HIGH OR LOW ACTING

The action of alarm #1 may be programmed to activate either when the display value goes above the alarm value (high acting) or goes below it (low acting).

“Act-1” < > “HI” or “LO”

AUTO OR MANUAL RESET FOR ALARM #2

The reset action of alarm #2 may be programmed to reset automatically (unlatched) or be programmed to require a manual reset (latched), through either a remote input (E1-CON or optional E2-CON)or through the front panel. Latched alarms are usually used when an operator is required to take some action for the alarm condition.

“LAtC-2” < > “yES” or “NO”
