4.4. Function of electrical control
4.4.1. Standard control
The standard version of the electrical control features a display where the current states of the plant are indicated
by means of LEDs. The control is equipped with a floating general alarm contact that is available as an NO or as an
NC contact. The control can be linked with the compressor control as described in “2.3.2.5. Intermittent operation”.
This option is particularly energy-efficient for intermittent compressor operation, as the adsorption dryer is only in
operation while the compressor is running.
4.4.2. Load-dependent control (dew point control)
This electronic control option allows for a range of programming and configuration options. The plant can thus be
programmed and configured to meet specific requirements, so that cycle times are optimised and regeneration air
consumption is minimised while operational safety is maximised.
The relevant control parameters can be configured directly in the control.
This ensures that the plant is optimised for the actual requirements and site conditions.
A general error signal can for example be sent through a floating contact to a process control system. In addition,
the control is equipped with an input port as standard, so that signals can be exchanged with the compressor.
This option is particularly energy-efficient for intermittent compressor operation, as the adsorption dryer is only in
operation while the compressor is running.
The control system allows for dew-point controlled capacity control.
By installing a dew point sensor, dew point changes are detected quicker and more reliably. Energy costs are
reduced, and the adsorbent capacity is fully utilised, as the drying time is adjusted, preventing undesirable dew
point peaks.
The text display of the control unit indicates the current operating states as well as service and alarm messages in
plain text.
The electronic control unit is a modular system.
As all models feature a basic PCB, the standard control unit can be upgraded with dew point control.
Plants featuring the previous control unit version can be upgraded with one of the latest generation, as all control
units have the same dimensions.
