Analog Input Sensors
Sensor Active This parameter governs whether the sensor will be monitored by the PMS II. Entering a
"1" will deactivate the sensor, the system will stop monitoring this point, and the bar will be replaced by
a "DEACTIVATED" message. Entering a "O" will reactivate the sensor.
Reference Marker The reference marker is an inverted white triangle on the bar grid, and it may be
used to mark any point on the grid important to the operator. Enter the numerical scale point where
you desire this marker to appear. This parameter has no operational significance to the PMS II.
Low Limit Setpoint Right pointing triangle. Any time the sensor reading falls below this setpoint, an
alarm sequence will begin. Enter the numerical scale point (if any) where you desire this to take place.
High Limit Setpoint Left pointing triangle. Any time the sensor reading rises above this setpoint, an
alarm sequence will begin. Enter the numerical scale point (if any) where you desire this to take place.
Schedule Log Enable Each sensor can be individually enabled or disabled from being logged on the
Printer during a Schedule log.
Alarm Delay The alarm delay is set and counted down after the sensor display crosses an alarm
setpoint. if the sensor does not return to a normal reading by the time the alarm delay times out, an
alarm will be annunciated. Alarm delays are adjustable from one second to 127 seconds.
Bar Filter The System maintains a running average (digital filter) of all analog data. The bar filter is
the number of previous readings averaged to obtain the current data value. it can be adjusted from 1
to 15. Scan Rate This selects how often the sensor will be read by the System. The scan rate is used
only to multiply the bar filter on non-Rate analog channels.
Offset The offset is the number of voltage counts the System uses to zero the analog signal, so that 0
count indicates the lower limit of the display range. Range is from -3840 to +3840. NOTE: The
magnitude of the negative offset can never be greater than the span.
