OPTION COMPONENT LAYOUT
EXPLANATION
The HVAC Relay Option Module can be used in applications
where two indicators are required showing “drive running”
and “drive tripped”.
Product Suitability
There are 2 variants of this option. The correct variant must be used
with the following products:
Optidrive
OD-HVACO-IN
Optidrive E
ODE-HVACO-IN
Optidrive size 2
Option PCB inserted into
Optidrive control terminal
strip.
All 11 terminal screws on
the Optidrive must be
tightened to ensure good
electrical contact and
correct functionality.
OPTION MODULE CONTROL TERMINALS
* Analog inputs should be connected to terminals 6 & 7.

NOTES
OPERATION
Programming the first relay output
For typical operation set P-18 = 1, eg Relay 2 closed on enable
(Drive running – Green Light), Relay 1 closed when drive tripped
(Red Light).
Use the following information to set P-18 for other types of Relay
output:
Since the first relay output (fitted within the Optidrive) is
programmed using P-18 in the Optidrive, two completely
independent relay outputs are available. The following options are
supported for Relay 1 :
P-18 = 0
Relay 1 closed when Optidrive disabled
P-18 = 1
Relay 1 closed when Optidrive tripped
P-18 = 2
Relay 1 closed when Optidrive output not at set
(requested) speed
P-18 = 3
Relay 1 closed when Optidrive output is at zero speed
P-18 = 4
Relay 1 closed when Optidrive output is not at maximum
speed
P-18 = 5
Relay 1 closed when Optidrive output is not in overload
Programming the second relay output
The second relay output has only one practical setting -
When P-18 = 1, Relay 2 is closed when Optidrive is running
