Automatic changeover panels for twin fans
ACOP ACSW 1 Automatic changeover panelACOP 1 Specification Ref. No. 7710 Features Automatic changeover panel with automatic duty sharingACSW 1 Suitable for use with Helioselectronic and auto transformerspeed controllers (accessory). Casing Impact resitant polymer casing
finished in white. Ref. No. ???? Suitable for use with twin fanswhere one fan is running and
the other is on stand-by, ensuringcontinuous ventilation in theevent of motor failure. Features Volt free contacts for remoteindication. Protection Suitable for use with twin fanswhere one fan is running andthe other is on stand-by. Ensuring
continuous ventilation in the
event of motor failure with duty
sharing. Protection to IP 65 Specification Operation Casing The unit detects the current ofthe fan circuit and switches tothe stand-by fan if the current in
the first fan is too low. Impact resitant polymer casingfinished in black and white. Automatic changeover in eventof motor failure. Automatic change over in eventof motor failure or flow using anexternal switch (e.g. airflowswitch). Protection Manual change over using theswitch on the face of the panel. Protection to IP 40. Motor Protection There are fuses in the unit for protection in case of short Operation Suitable for use with Heliosspeed controllers ESA 3 INDand ESA 6 IND (accessory). The unit detects the current of
the fan circuit of external switch
(airflow) and switches to thestand-by fan if the current in thefirst fan is too low. Or when the
switch is open using an external
switch or airflow switch (accessory). circuit. Motors must be protectedseperately by a suitable motor protection unit (accessory MW). Automatic duty sharing timebetween 2 and 24 hours. Visual indication of power onand fan failure. Automatic diagnostic programon start up of panel checks system. Fuses in the unit provideprotection in case of short circuit.Motors must be protectedseperately by a suitable motorprotection unit (accessory MW). Can be used with a run on timer(accessory ZNE). Duty share cycles Adjustable options 8 minutes
and 2, 4, 6, 10, 12 and 24 hours. Visual indication of fan runningand which fan has failed if any. Motor Protection Automatic start up sequence
runs both fans to ensure they
are both operational. Fuses in the unit provideprotection in case of shortcircuit. Motors must be protectedseperately by a suitable motorprotection unit (accessory MW).
