Introduction - Autogrow EC Mini Installation And User Manual

Introduction

The EC Mini Controller is from a family of monitors and dosers that have been
proven over many years. This controller has built upon this pedigree of simplicity
and innovative features.
Features
The EC Mini Controller may be used as a simple monitor or may have two
peristaltic pumps added to turn it into a complete dosing control system.
Failsafe Dosing
Dosing may be inhibited if any of the following is detected:
• EC outside limits detected
• Dose count per hour exceeded (DC/h)
These are useful if a leak should develop or the pump fail and should prevent
continuous dosing.
Alarms
The alarms can be enabled to operate on the controller when the EC or DC/h
deviates outside the user setpoint.
Outputs
The 24VDC outputs allows direct drive of 24VDC peristaltic pumps. Always ensure
that the current capability of the power adapter is greater than the current draw
of the pumps. The pumps that we supply take a peak current of 1.2A. The
controller is normally supplied with a 2.5A power supply.
