MAXIMUM METERING TIME
The maximum metering time is an extra function that ensures that metering operations are completed within a certain time
limit selected by the operator. The relays connected to the metering pumps activate accordingly. This function makes it possible to
eliminate time limits, to meter continuously based on the selected setpoints or, if the operator wishes to change the settings, to choose a
given period within the selected hours (up to 999 minutes).
START/STOP TIMES
The Timer in real time makes it possible to control through a timer the AUX outputs for each remote device, for the period selected
in the program. The operator may also program the days of activity and the exact time of the unit’s operations through the Start/Stop
programming.
AUX OUTPUT
The auxiliary output controls various functions connected to any type of remote On-Off device controlled by a timer in real time. Each
output is able to control a device or appliance thanks to very accurate programming of minutes/hours/days/weeks.
ADVANTAGES: this function makes this instrument a very versatile control unit not only to measure chemical physical parameters but
also for other functions connected to the system where it is installed.
START-UP DELAY
The start-up delay stops the output relays when the unit is switched on, thus allowing the sensor to polarise assuring correct
measurements (programmable).
FLOW SENSOR “Proximity Sensor”
Flow Sensor: if there is no water flow in the probe socket (and possibly in the system), the flow sensor (proximity sensor) disables
all outputs ensuring no chemical substance is added (DISABLED by default).
TEMPERATURE
Manual / Automatic Temperature offset (the latter with a PT100 temperature sensor) 0-100°C, the pH measurement will be offset in
temperature, always obtaining more accurate values.
ETHERNET / RS485 communication control unit with external module
The eSelect M series is suitable for remote control thanks to an RS485 expansion board with Modbus protocol using the ETACLOUD
software. The control unit via RS485/ETHERNET connection allows the operator to connect to the unit via a PC, a smartphone or a tablet,
change and view the programming and settings using the ETACLOUD software. The unit sends an email message once the alarm level,
overdose settings are reached, or when the maximum metering time of the metering pump has elapsed.
