E32.0.93.6C-02 Manual for connection and operation of the JDI-22 page 4 of 10
2. Introduction
The JDI-22 is a microprocessor controlled displaying, monitor-
ing and controlling device.
The device is supporting one input for the connection of a
Pt100 measuring probe
The device features two switching outputs, which are config-
ured as 3-point-controller.
The state of the switching outputs (relays) is displayed with the LED’s “1” and “2”.
Furthermore the device supports one interface for communicating with a host computer.
When leaving our factory the JDI-22 has been subjected to various inspection tests and is completely cali-
brated.
Before the JDI-22 can be used, it has to be configured for the customer’s application.
Hint: In order to avoid undefined input states and unwanted or wrong switching processes, we sug-
gest to connect the device’s switching outputs after You have configured the device properly.
Hint: By calling a configuration menu for offset- and slope-adjustment the measurement and regula-
tion of the device will be deactivated.
By leaving the menu the device will be reinitialised and the measuring/regulation will be started
again.
3. Electric Connection
Wiring and commissioning of the device must be carried out by skilled personnel only.
In case of wrong wiring the device may be destroyed. We can not assume any warranty in case of
wrong wiring of the device.
