External DUTY Adjuster
Note: 1. A temperature controller with relay output or a single relay can be used with the G3PX
in two-position (high-and low-position) control, in which case the relay contact current
is 30 mA at 12 VDC with the External DUTY Adjuster set to 0
Ω
.
2. Use a right DUTY adjuster (2- or 3-k
Ω
type) according to the G3PX model as follows:
G32X-V3K (3 k
Ω
) for EH-series models
G32X-V21K (2 k
Ω
) for EUN-, EHN-, and EC-series models.

j
0EUN Series)
The base-up output can be adjusted with the base-up adjuster knob. It is also possible to control the base-up output for the full scale of 4 to
20-mA input current by adjusting the duty adjuster. Refer to
Engineering Data on page 67 for the base-up characteristics.

Setting
1. Use the G32X-CT
jj
HN CT Unit and make sure that the
G3PX is wired correctly.
2. The G3PX initially set is shown in the following illustration.
Make sure that the RUN/SET switch has been set to SET.
Make sure that the DUTY adjuster has been turned clockwise
to the maximum.
