Iontypeset-up
Valence of ion types are divided into X--/X-/X+/X+ . When you measure ion in X-or X+
(valence=1), for example “F-“, please set the valence =1 in the ion type set-up. When you
measure ion in X--or X+ (valence=2), for example “Ca -“, please set the valence =2 in the ion
type set-up.
Note: Slope limitation for ion valence =1: 40～70mV.
Slope limitation for ion valence =2: 20～35mV.

Wrong wiring will lead to breakdown or electrical shock of the instrument, please read this
operation manual clearly before installation.
zMake sure to remove AC power from the controller before wiring input, output connections,
and remove it before opening the controller housing.
zThe installation site of the controller should be good in ventilation and avoid direct sunshine.
zThe material of signal cable should be special coaxial cable. Strongly recommend using our
coaxial cable. Do not use normal wires instead.
zAvoid electrical surge when using power. Especially when using three-phase power, use
ground wire correctly.
zThe output terminals of the controller are designed for alarm and control function. Due to the
safety and protection concern, please be sure to connect current-sufficient relay to load with,
in order to ensure the operation safety of the instruments.(Please see chapter 3.6--Electrical
connection diagram)
3. Assemblyandinstallation
3.1 Controller installation: This controller can be installed through panel mounting, wall
mounting and pipe mounting.
Installation of panel mounting: First,prepare a square hole of 138 x 138mm on the panel box,
and then insert the controller directly into the panel box. Insert the accessorial mounting
bracket from the rear, and make it be fixed in to pickup groove.
