1.5. Proper use
The BEKOMAT® is an electronically level-controlled condensate drain for compressed air systems. The BEKOMAT®
is able to drain condensate from the plant components at operating pressure and with virtually no compressed air
loss. The BEKOMAT® version with no-load drain/no-load valve caters for plants with low operating pressure, for
instance in connection with multi-stage compressors.
This model must always be equipped with original spare parts and accessories.
The BEKOMAT®3/6 CO Ex or 3/6 E Ex can be operated in potentially explosive atmospheres, provided that the
unit bears the following ATEX-/EPL mark:
II 2G Ex ib IIB T4 Gb
Admissible media: Ethane, methane, coal gas (town gas), compressor oils, diesel fuel, ethylene,
propane, heating oil, uid of DGRL group ll
For more information regarding the ATEX classication and mark, see 2.6.1, page 14.
Do not install the BEKOMAT® in areas that are exposed to frost.
Operate the unit only for the intended purpose and within the limit range specied in the technical data. Do not
operate the unit with any media (uids, gas/vapour mixtures) than those listed above. Any other use of the unit is
deemed improper and poses a risk to persons, property and the environment.
1.6. Warranty and liability
All warranty shall be voided, if the BEKOMAT® is used improperly, for a purpose other than the intended or is
operated outside the limits specified in the technical data. In such cases, the manufacturer shall also reject any
liability for damage. Improper operation includes:
• Incorrect installation, commissioning or operation; insu󰀩cient maintenance
• Operation with defective components
• Non-compliance with the instructions in this document, in particular the safety instructions
• Modication of the unit
• Use of third-party spare parts that have not been approved by the manufacturer

Alarm mode:
The BEKOMAT® is continuously monitored by electronic and sensory devices. If a fault or malfunction occurs, the BEKOMAT® is
automatically switched to alarm mode (e.g. due to blocked condensate discharge, or overload). In alarm mode, the solenoid valve is
automatically opened, starting in cycle mode in order to eliminate the problem. If the problem persists for more than one minute, the
red alarm LED flashes and the optocoupler output is switched. The valve is then repeatedly opened every four minutes for 7.5 seconds,
until the problem is resolved automatically or by servicing the unit. After the problem has been resolved, the BEKOMAT®automatically
switches to normal operating mode.
