Measuring channels 1 and 2 are located on the basic module
(module A). Channel 3 is optional and is located on the extension
module (module C)
The digital inputs 1, 2, 3 and 4 are located on the basic module
(module A).
The digital inputs 5, 6 and 7 are on the optional extension module
(module C).
If a sample water error is pending, then metering of the selected
channels is immediately stopped. An alarm is emitted, the display
lights up red, an alarm relay is activated, and the alarm relay drops
out. Once the sample water error has been rectified, then the error
status is reset, and the controllers restart according to the switch-
off delay set.
When the Pause input is set, then metering immediately stops and
all the control outputs are set to 0%. When the Pause input has
been reset, then the controllers restart according to the switch-off
delay set. The last current I-factor has been saved and the I-factor
is added to the P-factor currently calculated.
When the Pause Hold input is set, then the control outputs are
frozen in the status prior to "Pause Hold". When the Pause Hold
input has been reset, then the controller restarts according to the
switch-off delay set. The last current I-factor has been saved and
the I-factor is added to the P-factor currently calculated.
You can configure the mA outputs as a measured value in such a
way that the mA outputs either switch to the actual measured value
before Pause/Pause Hold or to a fixed value when
Pause/Pause Hold is enabled.
