Description
Clorius ER 2000 Electronic Controller
The ER 2000 controller is used for constant temperature control. It is suitable for all heating and cooling control systems. The controller is primarily intended for marine installations and other industrial applications – such as cooling water and lubricating oil installations, flow temperature control etc.
The ER 2000 controller is designed for panel mounting. For easy start-up it has optimization for automatic determination of favourable control parameters. The optimization starts when changing the set point or when switching over from manual mode to automatic control.
The optimization can be disregarded. For easy operation it has three keys – two for scrolling or changing values and an enter key. Two digital displays show the process variable and the set point. 3 LEDs indicate actuator opens, actuator closes and alarm. The controller can be switched from auto mode to manual mode.
In manual mode the actuator can be opened, closed or stopped in a certain position.
Three different alarm settings are possible:
A: Alarm at a deviation from the set point SP
B: Alarm at a fixed limit value
C: Alarm at leaving a band around the set point SP.
It can operate either as a three position or as a two position controller or analogue (4-20 mA) controller and has adjustable proportional band, integral action time and derivative action time.
