IDLE MODE
During idle mode the device performs only measurements
but it does not activate relays in order to control the process
or let out a control signal to the analog output .
In a normal situation the alarm relay is energized (no alarm
condition) and the green LED is ON, the red LED is also
fixed ON to warn users the device is not controlling the
process, the yellow LEDs are OFF .
Moreover, the alarm relay could be de-energized upon
an error (whether that happens or not, depends on the
customized alarm configuration; see “Alarm” section for
more details) . Nevertheless, the error due to alarm thresh-
old overtaking does never generate an alarm during idle
mode since all the control functions have been disabled
by the user .
The red LED flashes in any case upon an error .
Idle mode is useful to disable control actions when the
external devices are not properly settled or whenever any
fault circumstance is detected .
To set the meter to idle mode it is sufficient to disable the
control mode (setup item C .00 to “OFF”) .
When measurements are in overflow, the upper or lower
range limit is shown on the LCD with blinking digits .
