Manual Overrides as per EN ISO 16484-2:2004
The manual override switches and potentiometers of the output modules support direct operation as per EN ISO 164842:2004, section 5.4.3 "Local Priority Override/Indicating Units."
Specifically, the positions of the manual override switches and potentiometers directly control the outputs – independently
of the controller and HMI. When a manual override switch or potentiometer is not in its default position ("auto"), the
corresponding output LED will blink continuously, and the output module will send a feedback signal with the status
"manual override" and the given override position to the controller (which will then also store this information in its alarm
memory).
NOTE: When updating the firmware of output modules, their outputs are turned OFF – regardless of the position of their

Overvoltage Protection
The inputs and outputs of all CentraLine analog and binary
I/O modules are protected against short circuit, 24 VAC
+20%, and 40 VDC.
In the case of the relay outputs of other CentraLine I/O
modules (i.e., relay output modules, floating output modules,
and mixed I/O modules), appropriate fusing must be provided
to ensure that permissible load currents are not exceeded.
See also sub-section "Features" in section "Relay Output

Service LED
Each LONWORKS Bus I/O Module is equipped with a yellow
service LED (status: yellow/OFF) for easy diagnosis of
failures.

Current Requirement and Heat Dissipation
The LONWORKS Bus I/O Modules are equipped with highlyefficient switching power supplies which provide for relatively
uniform power consumption over a wide range of supply
voltages (see Table 6). The specific heat dissipation inside
the modules amounts to less than 2 W for all models.
