6.2 Type key
The example shows a controller for electrically driven pumps in
accordance with EN 12845 with a motor output of 15 kW.
7. Technical data
Inputs
The controller has four digital inputs. See table below. The table
also states terminal designations and the status when activated.
The digital inputs are not short-circuit proof.
Outputs
The controller has five digital outputs which are potential-free
changeover contacts. The signals from the digital outputs can be
passed on to a building management system.
Electrical data of signal relay outputs
8. Control panel
The control panel is divided into three areas:
• operating buttons
• status indicator lights
• fault indicator lights.
