Cycle Time The time base for the time proportioning outputs

entered in seconds. For example with a 10 second
cycle time, and 30% output, the output will be on
for 3 seconds and off for the balance of 7
seconds. DeadbandAlarm hysteresis value. A value
entered will cause an alarm to remain on or set
until the process variable comes out of alarm by
at least the value of the deadband. The purpose
of the deadband is to avoid nuisance alarms when
the process is approximately the alarm value.

Deviation A high and low alarm band that moves with the Band
Alarm
setpoint.

Error Check The method of communications error checking

performed by the communications protocol handler.
May be BCC (Block Check Character) or CRC (Cyclic
Redundancy Check). Default is BCC.

High Process A fixed alarm level that goes into alarm when the
Alarm process measurement is higher than it's setting.

Input Type The sensor type connected to an input.Thermocouple

types are designated by their letter, linear
should be used for all other types.

Job A set of operating conditions for all 8 loops

including setpoints, loop status, output levels,
alarm configuration data and (if installed)
associated ramp/soak profile assignments. Up to
eight jobs can be stored in the 8LS.

Low Process A fixed alarm level that goes into alarm when the
Alarm process measurement is lower than it's setting.

ManualMode The loop mode in which the PID control outputs are

set manually by the operator.

Output Type PID control output type such as Time Proportioning,

Distributed Zero Crossing , ON/OFF or Analog.

Panel Lock Feature allowing the function keys on the front

panel to be locked out.

PB Proportional control band of the PID in the

engineering units of the input.

PROM Version The release number and date of the PROM inside the

ANAFAZE controller.

Ramp/Soak Time The time base used in ramp/soak profile segment

timing. May be either hours and minutes or minutes
and seconds.
