Confirmation of Detector Type Setting
Check that the detector in Figure 7.7 is the one for this equipment.
DANGER
• If this converter is to be used in conjunction with the ZO21D, the power requirements
are limited to 150 V AC or less, 50 Hz or 60 Hz (it cannot be used with a 150V or
greater, or in the EEC).
If detector settings are to be changed, first disconnect the wiring connections between
the detector and the converter. Then change detector settings appropriately.

Current Output Setting
This section sets forth analog output settings. For details, consult Section 8.1,“Current
Output Settings,” later in this manual.
7.7.1
Analog Output Setting
Select any one of the analog output settings — Oxygen, Humidity, and Mixing from the
mA-output range display. If the /HS option is specified at the time of purchase, the
equipment is a humidity analyzer. For other than this setting, the analyzer is an oxygen
analyzer. If a mixed measurement is required, change the current output setting as given
below. If the humidity analyzer is specified in the above detector type setting, the analog
output is set to “humidity” when the data initialization is attempted.
(1) Select the Setup from the Execution/Setup display.
(2) From the Commissioning (Setup) display, select “mA-output setup”; the display
shown in Figure 7.9 then appears.
(3) Select “mA-output1” from the “mA-outputs” display. The “mA-output1 range”
display shown in Figure 7.10 then appears.
(4) Select the Parameter, then the Oxygen, Humidity, and Mixing appear in the mA-
output1 range display (Figure 7.10.1). Select “Mixing” and press the [Enter] key.
(5) The “Mixing” in Figure 7.10.2 appears.
(6) Perform the same setting in mA-outpout2 if necessary.
Both outputs are 4-20mA
