ER2000 Electronic Controller

ER2000 Electronic Controller

2183

The Clorius ER 2000 electronic 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. Design The ER 2000 controller is designed for panel mounting. For an easy start-up, it has optimization for the 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 setpoint. 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: Alarm at a deviation from the setpoint SP Alarm at a fixed limit value Alarm at leaving a band around the setpoint SP It can operate either as a three-position or as a two-position controller or analogue (4-20 mA) controller and has an adjustable proportional band, integral action time and derivative action time. Function The temperature input comes via a Pt 100 sensor with a single sensing element. The measured value of the controlled variable is compared with the setpoint value and adjusted via a PI or a PID control structure. The ER 2000 can act as either a heating controller, the actuator closes at rising temperature, or as a cooling controller, the actuator opens at rising temperature. The ER 2000 permits direct reading of the actual temperature value (PV), and it is secured from failure in the measuring circuit, i.e. the controller can be set to give either a closing, an opening, or remain in current position command in case of sensor short circuit or sensor break. The error message Err appears in the LED display PV.

KPS Pressure Switch & Thermostat

KPS Pressure Switch & Thermostat

5306

The Danfoss KPS thermostat and pressure switch series consists of a series of pressure and temperature controlled switches. In the Danfoss KPS series, special attention has been given to meeting demands for a high level of enclosure, robust and compact construction, and resistance to shock and vibration. For the Danfoss KPS pressure switches, the position of the contacts depends on the pressure in the inlet connection and the set scale value. For KPS thermostats, the position of the contacts depends on the temperature of the sensor and the fixed scale value. The series covers most outdoor and indoor application requirements and is suitable for use in monitoring alarm and control systems in factories, diesel plants, compressors, power stations, and board ships. Available types: Danfoss KPS 76 Pressure Switch and Thermostat Danfoss KPS 77 Pressure Switch and Thermostat Danfoss KPS 79 Pressure Switch and Thermostat Danfoss KPS 80 Pressure Switch and Thermostat Danfoss KPS 81 Pressure Switch and Thermostat Danfoss KPS 83 Pressure Switch and Thermostat

MBC 8000 / 8100 Thermostat

MBC 8000 / 8100 Thermostat

5315

The Danfoss MBC 8000 and MBC 8100 thermostats designed for use in severe industrial and marine applications where space and reliability are the essential features. MBC 8100 have all international marine approvals. According to Danfoss block design, both MBC thermostats are designed to survive in the harsh conditions known from machine rooms, among others. In addition, the Danfoss MBC 8000 and Danfoss MBC 8100 have high vibration resistance. The sensor on MBC 8100 thermostat contains an adsorption charge. Therefore its function is not affected whether the sensor is placed warmer or colder than the remaining part of the thermostatic element (bellows and capillary tube). However, a charge is sensitive to changes in the temperature of the bellows and capillary tube. Under normal conditions, this is of no importance, but if the thermostat is used in extreme ambient temperatures, the setting point might change.

ER3000 Electric Controller

ER3000 Electric Controller

9175

The Clorius ER 3000e electric controller is used for constant temperature control. It is specially designed for large engine jacket cooling water systems where conventional single loop controllers cannot maintain a constant and precise temperature. The ER3000 controller operates with TWO sensor inputs. One Pt 100 sensor is placed at the outlet from the engine and one Pt 100 sensor with a built-in 4-20 mA transmitter is placed at the inlet to the engine. The measured values of the controlled variables are compared with the setpoint value and adjusted via a PI or a PID control structure. Design The ER 3000 controller is designed for panel mounting. For an easy start-up, it has optimization for the 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 four keys – two for scrolling or changing values, an enter key and a key for choosing manual or automatic control. Two digital displays show the process variable and the setpoint. 7 LEDs indicate alarm, the actuator opens, actuator closes, slave control, setpoint raising/lowering and manual mode. 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: Alarm at a deviation from the setpoint SP Alarm at a fixed limit value Alarm at leaving a band around the setpoint SP The 3 alarm settings include an alarm in case of a sensor fault. It can operate either as a three-position or as a two-position controller and has adjustable proportional band, integral action time and derivative action time.
