Recorder Output
The proportional value of a channel that is sent to the 4 to 20 mA recorder.
The recorder output is proportional to the measured value over the channel
full-scale range. An increase in the proportional value that would be
indicated as upscale on a bar graph display results in an increase in the
current at the recorder output. If the channel is Bypassed, the output will be
clamped to the selected clamp value or to 2 mA (if the 2 mA clamp is
selected).
OK Mode
Latching
If a channel is configured for Latching OK, once the channel has gone not
OK the status stays not OK until a reset is issued. Reset a latched not OK by
using one of the following methods:
- the reset switch on the front of the Rack Interface Module
- the contact on the Rack Interface I/O Module
- the Reset button in the Operator Display Software
- the reset command through the Communication Gateway Module
- the reset command through the Display Interface Module
- the reset command in the Rack Configuration Software
Nonlatching
The OK status of the channel will track the defined OK status of the
transducer.
Timed OK Channel Defeat
An option that prevents a channel from returning to an OK status until that
channel's transducer has remained in an OK state for the specified period of
time. If the option is enabled, the time is set to 10 seconds. The option protects
against false trips caused by intermittent transducers.
Delay
The time which a proportional value must remain at or above an over alarm level
or below an under alarm level before an alarm is declared as active.
Alert
First level alarm that occurs when the transducer signal level exceeds the
selected Alert/Alarm 1 setpoint. This setpoint can be set on the Setpoint screen.
The Alert time delay is always set at one second intervals (from 1 to 60) for all
available proportional values.
