When deviation low-acting with positive alarm value (d-LO), deviation high-
acting with negative value (d-HI), or band inside-acting (b-IN) is selected for the
alarm action, the indicator is OFF when the alarm output is ON. See the Alarms
section for complete details of each action. If changed, check alarm values.
Automatic reset alarms are reset by the TLA when the alarm condition clears.
Latched alarms require operator action to reset the alarm condition. The front
panel R button, if enabled, can be used to reset a latched alarm (see FPrS in
Configure Module 3). A latched alarm condition may also be reset via the
Remote Reset input. See the Reset Action diagram in the Alarms section.
The alarm(s) may be independently configured to exhibit a power-on, standby
delay which suppresses the alarm output from turning ON until the temperature
first stabilizes outside the alarm region. After this condition is satisfied, the alarm
standby delay is canceled and the alarm triggers normally, until the next TLA
power-on. This feature also works for deviation and band alarms when the
setpoint is changed via keypad. This action suppresses “nuisance” alarms. See
the Alarm Standby diagram in the Alarms section.
The alarm values are either absolute values, or relative to the limit setpoint value
(deviation and band alarms). An absolute alarm value is the value that is entered
for the alarm. A relative alarm value is the mathematical sum of the temperature
limit setpoint value and the alarm value (positive or negative), thus a relative
alarm tracks the limit setpoint value as it is changed. If the alarm action is set as a
Band Alarm, then only a positive alarm value can be entered.
The Alarm 2 parameters are programmed independently of alarm 1. See the
corresponding Alarm 1 parameter for description.
The alarm value(s) have a programmable hysteresis band to prevent alarm
output chatter near the alarm trigger point. The hysteresis value should be set
to eliminate this effect. A value of 2 to 5 is usually sufficient for most
applications. A single alarm hysteresis value applies to both alarms. See the
Alarm Action Figures, in the Alarms section, for the effect of hysteresis on the
various alarm types.
The password is required to access all parameters. The password can be
set to any value between 0 and 250. A wildcard password, 222, can be
used as an alternative to the programmed password.
The alarm(s) parameter in the Parameter Mode can be configured to be
completely locked out, read only, or fully accessible.
The front panel R button can be enabled or disabled. The Remote Reset
input is not affected by this setting.
