Rotary direction
•
The arrow direction must match the rotational direction of
the actuator.
•
Factory setting:
Self-adapting
0
•
Alternative switch-on/off for self-adaptation.
: ON
0: OFF
•
Factory setting: 0
CAUTION:
When turning the self-adaptive feature on, or after a
software reset with the feature on, the actuator will
enter a five-minute calibration cycle as the actuator
adjusts to the rotation limits of the system.
A software reset happens after power on, or may be
caused by electrostatic discharge (ESD) at levels of
2kV and above.
Positioning Control Signal
: (GEB161)
2-10
0-10

Alternative settings:
2-10 Vdc
0-10 Vdc
•
Factory setting: 0-10 Vdc
Positioning Control Signal:
(GEB164)
ADJ
0-10
•
Alternative settings:
ADJ: Allows offset/span adjustment capability
0-10V: Ignores offset/span capability and provides
0-10 Vdc input signal only
•
Factory setting: ADJ
Wiring
All wiring must conform to NEC and local codes and regulations.
Use earth ground isolating step-down Class 2 transformers. Do not use autotransformers.
The maximum rating for a Class 2 step-down transformer is 100 VA. Determine the supply transformer
rating by summing the VA ratings of all actuators and all other components used. It is recommended
that one transformer power no more than 10 actuators (or 80% of its VA).
WARNING:
Mixed switch operation is not permitted to the switching outputs of both auxiliary switches
(A and B).
Either all six outputs of the dual auxiliary switches must be connected to the AC line
voltage, or all six outputs must be connected to UL-Class 2 voltage (SELV for CE
conformance).
NOTE:
With Plenum cables only UL-Class 2 voltage (SELV for CE conformance) is
permitted.
