Installation/Data Sheet Supplied
Note: The relay is shown in the de-energised condition.
Installation and Setting
* Connect
the Unit as shown in the diagram. (Ensure the correct terminals are used
when connecting to the supply).
* Select the required temperature range. (N.B. fit link between terminals
'Y1' and 'Z' for 200 to 300°C range).
* Set the relay inversion switch to either 'N' (Normal) or 'I' (Inverted).
* Apply power (green LED on).
Analogue Outputs
* Connecting between terminals 'Y1' and
'X1' provides DC voltage relative to the set point
(i.e. set point @ 20% = 2V DC out).
* Connecting between terminals 'Y1' and 'X2' provides DC voltage relative
to the measured temperature within any range selected. |
