Potential-free contact
The alarm signal can be relayed via a
potential-free contact. The changeo-
ver contact can be operated, e.g., in
the fail-safe mode.
When operating voltage is being app-
lied and the BEKOMAT device is
functioning correctly, the alarm relay
is energized. The contact element
(N.O.– COM).
When there is no operating voltage or
in the case of a fault signal, the alarm
relay drops out. The contact element
is open (alarm).
Externernal Test button (optional)
Here, the normal test button function
has been extended for additional use
outside the BEKOMAT unit. This
makes it possible to discharge any
condensate in the unit by remote
control, if required. When the external
contact closes, the valve will open.
Before maintenance work always
ensure that the device is:
• pressureless and
• de-energized.
Maintenance recommendation:
• Remove 2 pan head screws (1) and
lift off BEKOMAT. The elbow adap-
tor stays in place.
• Disconnect discharge hose (2).
• Turn the 6 pan head screws (3) until
heads are level with the outer edge
and take off diaphragm seat (4).
• Replace wearing parts
• Reassemble BEKOMAT unit in re-
verse order.
