8.2.4 Energy management options

See 8.1 for connection of the PC to the controller. The

energy management active box will be unticked and the

feature therefore disabled. Energy management is

activated by ticking the ‘Energy Management Active’ box.

The energy management feature can be deactivated by

unticking the box if necessary. Alternatively, the DIN plug

with jumper link will override the energy management

feature providing it is left in place.

Select dry or wet receiver from the illustration given in the

set-up screen by toggling in the appropriate box.

Note: for point of use dryers or constant running dryers

utilizing dewpoint monitoring the dry receiver system

should be activated regardless of installation.

By switching “dryer receiver” this will operate the energy

management facility after a 15 seconds delay.

For wet receiver applications switch the wet receiver box. To calculate the necessary delay it is

necessary for the installer to input the high and low pressure set points for the compressor

switch, the internal volume of the receiver and the flow rate of the dryer. The purpose of the

delay is to prevent dryer saturation when using a large receiver with large range of set

pressures.

Once the application conditions have been input click “OK” this will return the screen to

main application software click “Program Dryer” will set and fix the previously defined

conditions.

The RS232 connection can be removed by using a small screw driver to depress the retaining

tang on the connector and withdrawn. Replace the push-in cover and replace the front

panel.

8.2.5 Energy management memory retention

Energy savings are made in the dryer by interrupting the normal purge operation during

periods of low demand.

To maintain the equilibrium of the dryer towers the dryer has a memory retention

feature. This allows the dryer to remember the point in the operating cycle when the

energy management feature was activated and return to it to complete the cycle.

8.2.6 From new or service delay

To allow conditioning of the dryer desiccant beds to the optimum condition, a 6-hour

delay has been programmed into the controller to delay Energy Management operation

from new or from a service. Once this time has elapsed and the energy management

facility can then be operated.
