power line converter with relay output
(P/N 106 666 or P/N 111 014) provides a sim-
ple means of converting 85 … 265 VAC input
power to 24 VDC. This is required to power the
door protection light curtain or the IMS 100
while, at the same time, converting semi-
conductor outputs (NPN or PNP) to potential-
free (relay) contacts.
Additional change-over-relay is needed when-
ever the existing logic of the light curtain was
NC, i.e. whenever the elevator controller needs
a high level for “No object”.
If the existing light curtain already has a relay
output, you simply have to make a logical AND
conjunction of the two relay outputs.

Once the IMS 100 and associated door protection
system have been installed and wired in accordance
with your elevator control system requirements, turn
the power on and verify that the system operates as
expected. When the CEDES power line converter is
connected to 85 … 265 VAC, the green LED will be
illuminated to indicate that 24 VDC power is present
for powering the IMS 100 sensor and that the input
voltage to the power supply is greater than 85 VAC.
The IMS 100 has several IR-LEDs that are used for
infrared illumination of the area. If you look directly at
the sensor when it is under power, these LEDs will be
flashing constantly.
The IMS 100 also has a single red LED that provides
output status information (see 4.1). When this red
LED is illuminated (i.e. ON), the IMS 100 has detect-
ed a moving person or object and the output (black
conductor) will be inactive (low, e.g. 0 VDC). When
this LED is not illuminated (i.e. OFF), the IMS 100
has detected no person or object and the output
(black conductor) will be active (high, e.g. 24 VDC /
U
SP
). See Section 4, Troubleshooting for additional
information regarding other LED states.
Important note:
The IMS 100 is an intelligent sensor that bypasses
itself during door closure. There is no need for an
additional sensor(s) for door recognition. When
installed correctly, the IMS 100 remains active (i.e.
not bypassed) until approximately 100 ... 150 mm
prior to door closure.
