The analogue 4-20mA1 / 4-20mA2 outputs of the eSelect M follow the options previously selected of the CHLORINE SCALE
Please note that the displayed value is automatically adjusted according to the C hl ori ne S cal e range
previously set up.
The 4-20mA proportional analogue outputs are related to the measurements in real time in order to drive remote
equipment such as data loggers, PLCs or graphic recorders or other equipment suited to processing a remote
mA signal
Direct mode: the output is active when the measured value is lower
than the one selected in the setpoint.
Reverse mode: the output is active even if the measured value is higher
than the one selected in the setpoint.
The window width sets the distance from the setting point where the 4-20mA mode starts: 4mA = 0 metering pump pulse, 20mA =
max impulsive frequency of the metering pump. The window width depends on many variables: distance injection point, reaction time, chemical
% ....
With the overdose time alarm one can select a period during which the setpoint must be reached. If the setpoint
is not reached during this period of time, the instrument blocks output operations, including those in mA
(metering pumps), the alarm is displayed as ON and triggers a signalling instrument connected to the alarm
relay.
Maximum Metering is a safety function that ensures metering is completed
in the selected time. The relays of the metering pumps open accordingly.
This function makes it possible to eliminate time limits (continuous metering
according to the selected setpoints) or to select the minutes (up to 999) and
the hours, for instance metering for 999 minutes in 24 hours.
