Fig. 67. Manual overrides (rotary knobs)
The CLIOPR822A/CLIOLR822A Analog Output Modules are
equipped with manual overrides: one for each analog
output. These rotary knobs can be manually set to either
"AUTO" or "0…100%" (infinitely adjustable).
NOTICE
Damage to the electronic module!
► Do not use a tool to adjust the rotary knobs.
► Do not use excessive force. Adjust only by hand.
Manual Override in the AUTO Position
When a manual override of the CLIOPR822A/CLIOLR822A
is set to AUTO, and the corresponding analog output has
been configured, the following applies:
• If the LONWORKS network is functioning properly, the
output voltage of the analog output will be as
commanded.
• If the LONWORKS network is not functioning properly, the
output voltage of the analog output will be the safety
position value.
• The brightness of the status LED (red) of the analog
output will be proportional to the commanded output
signal.
When a manual override of the CLIOPR822A/CLIOLR822A
is set to AUTO, and the corresponding analog output has
not been configured, the following applies:
• Regardless as to whether the LONWORKS network is
functioning properly or not, the output voltage of the
analog output will be 0 V (values from the L
ONWORKS
Bus will be ignored, and there will be no heartbeat or
safety position).
• The feedback signal on the LONWORKS network
nvoAoActPosnFb[ ] will have a value of 0% and a state
of 0.
• The analog output status LED will be dark.
Manual Override in the Override Position (0…100%)
When a manual override of the CLIOPR822A/CLIOLR822A
is set to 0…100%, and the corresponding analog output has
been configured, the following applies:
• The output voltage of the analog output will be 0…10 V
(direct) or 10…0 V (reverse).
• The feedback signal on the LONWORKS network
nvoAoActPosnFb[ ] will have a value of 0…100% and a
state of -1.
• The status LED (red) of the analog output will flash to
indicate “manual override.”
When a manual override of the CLIOPR822A/CLIOLR822A
is set to 0…100%, and the corresponding analog output has
not been configured, the following applies:
• The output voltage of the analog output will be 0…10 V.
• The feedback signal on the LONWORKS network
nvoAoActPosnFb[ ] will have a value of 0…100% and a
state of -1.
• The status LED (red) of the analog output will flash to
indicate “manual override.”
Analog Outputs Configured as Binary Outputs
Using the engineering tool, the analog outputs can be
configured individually as binary outputs. The voltage output
is then 0 V or 10 V, depending upon the signal from the
controller.
