E2010 THYSSENKRUPP ELEVATOR Printed in USA February, 2010
Door Protection-5
The detectors have AMP connectors preinstalled which fit
onto the pin headers provided in the 280.
The Memco power supply provides:
S a regulated DC supply for the 640 detectors
S a relay output for connection to the door re-open circuit
S an audible tone when the light-curtain is broken (Note - this
can be disabled)
S Model 280 is powered from an AC supply (115V)
The Model 280 is factory-set for “fail-safe” operation using
standard PNP -N/C 640 detectors. However switches are
provided to allow detectors with other transistor configura-
tions to be used.
Direct Connection
The connectors are keyed and can only be installed in the
correct position. If forced incorrectly by the installer the
locking tab will be broken and can cause possible damage to
the detectors.
The 640 can be connected directly to the lift-controller or
door-operator if it has a suitable power supply and ”door
reopen” circuit. A special adaptor c able is required for
Thyssen lifts. The power supply must be regulated DC
(11-30V) with no transients. The door reopen circuit must
accept a transistor drive and the current must never exceed
100mA.
Contact Memco to discuss direct connection
in more detail.
