Sequetrol compact LCD details

Sequetrol compact LCD has been developed as a comfortable but economically priced control unit.

Equipment:

The extent of the system functionality and the design of the front panel of the Sequetrol compact LCD control unit can be tailored to match your individual needs.

The Sequetrol compact LCD is also available with features, such as, acoustic signaling of predefined conditions, a sequence program permanently stored in the EEPROM, and a set of batteries (optional NiMH rechargeable batteries) to ensure continuous signaling during power outage.

The built-in backlit 2x16 character LCD allows to have step names, alarm messages, operating hours and other user specific information, clearly displayed during operation.

When the control sequence is interrupted due to mains failure, the unit will automatically resume operation with the last unfinished step instead of restarting the program.

Utilizing the three buttons on the circuit board, the sequence timing can be readjusted at the installation site, resulting in an increased flexibility in adapting the Sequetrol compact LCDto the individual requirements of the particular plant.

Build-up of residual pressure in the valve unit is prevented by stopping the compressor before closing the valves. Timing is individually adjustable for each program step (0 - 14s).

Connections:

Available digital input can be used to connect a float-switch or another sensor.

Up to 5 relay outputs for 230VAC offer a comfortable connection of solenoid valves, diaphragm compressors or other loads.

Programming:

The programming process was developed especially with regard to the demands of a real application.

The control unit will be delivered ex-factory already pre-programmed according to customer requirements. Firmware updates and sequence program changes can be performed with the aid of an inexpensive programming device. This also makes the Sequetrol compact LCD “future-proof” and ready for possible changes of the legal situation.

No programming experience or any special software is needed.

The sequence program can be easily created or modified using a ready-made spreadsheet table (Excel®, OpenOffice® or similar).
