LC multi-function display with plain text display:
Different menu languages can be selected
Simple start-up by opeating modes:
You can choose between different operating modes, for example, external activation, temperature control, pressure control condensers.
Simple programmability:
Typical settings for the activation of fans and activation of the spraying stages can be made easily.
3 analog inputs for sensors or setting signals:
Analog input E1 and E2: Setting by operating modes or manually programmable, e.g. 0-10 V, 0-20 mA, 4 – 20 mA.
For input E2, special functions (external manual mode, external setpoint, measurement value for limit messages) can be programmed.
Input E3: To measure the outdoor temperature (the CKE-3ARV includes a TFR thermistor for this). Relay switching points for frost protection can be set depending on the outdoor temperature
6 digital inputs D1 to D6:
Setting by operating modes or manually programmable. Limit switches for valves, enable, switch over setpoint 1 or 2, external fault, control function inversion, output limitation, manual mode.
2 analog outputs A1 and A2:
Output A1: 0-10 V for activation of fans, e.g. by external speed controller (e.g. Fcontrol frequency inverter).
Output A2 manually programmable, e.g. 0-10 V proportional modulation, constant voltage, proportional input signal.
2 digital outputs (relays) K1 and K2:
Setting by operating modes or manually programmable. Spraying stages 1 / 2 / 3, activation supply cock/pump (frost protection), operating indication, fault indication,
limits, external fault at digital input.
