Setting Selectors and Switch
Observe the following precautions when operating the selectors and switch.
•
Always make sure the power is OFF before changing the selectors and switch.
•
Use a small flat-blade screwdriver to change the selector and switch settings,
and be sure that the selectors are correctly positioned.
2-3-1 UNIT Selector
UNIT INPUT
When serial communications are being used, the UNIT selector must be set so
that the host device can recognize the E5ZE unit number.
When more than one E5ZE Multipoint Temperature Controller is being used with
RS-422 or RS-485 communications, set a different unit number for each E5ZE.
•
The selector settings 0 to F correspond to unit numbers 00 to 0F. The factory
setting of 0 corresponds to unit number 00.
2-3-2 INPUT Selector

Set the INPUT selector according to the type of temperature sensor connected
to the E5ZE. The selector positions and corresponding temperature sensors are
