1. Explanation of product
1.1 Product outline
This product is the alarm setter of the plug-in structure which considers a DC voltage (or DC current) signal
as an input, and outputs the relay contact signal of four points (maximum) as compared with the set-up operation
set value.
This product is the type corresponding to the software that has a LCD function and a scale can set up arbitrarily
according to the amount of processes. The real scale display function of an input, the dead band setting function,
the contact delay setting function, and the starting delay setting function are built-in. It can correspond
to various process instrumentation flexibly.
1.2 Features of product
Setting accuracy is ±0.1％ (％ for input span). Display accuracy is ±0.1％±1digit (％ for input span).
Between input, output, auxiliary supply and cases, withstand voltage is AC2000V design.
The display of real scale by LCD. And, setting can carry out freely by the front button switch.
It can correspond to scaling change etc.
Nonvolatile RAM offers the power failure guarantee of the set value.
Sufficient derating of uses parts, and reduction of inside generation of heat improves reliability.
The back light is turned on at the case of key operation. 30 seconds after key operation is completed, the
back light puts out the light.
By the pre-alarm function, the efflux in contact delay time is displayed by blinking of a monitor lamp.
(ON/OFF of prealarm can be selected by setting.)

2.4 Prealarm function
A monitor lamp is blinked among contact delay time until excitation of a relay after operation value detection.
Blinking of a monitor lamp will be gradually fast, and when the point of contact delay time passes, a monitor
lamp is lights up.
If contact delay time setting is made into 0 second, a prealarm function constitutes OFF.

・The decimal point position change of scaling is made by the minimum value scaling.
If the decimal point position is changed, the decimal point position of maximum value scaling and operation values
1 to 4 will also change. If the decimal point position is changed, please be sure to check the set value of
a maximum value scaling and an operation value.
・An operation value can be set up in -25 to +125％ of the measurement display range (minimum value scaling to
maximum value scaling).
(Example) Input 4 to 20mA, Operation value -25.0, Output mode is "Low" setting.
It becomes L detection in 0mA of inputs, it is also possible to use it as
disconnection detection.
・After setting change, in case a set value combination error occurs, it becomes a setting error display.
Please push the key and set up the right set value (in set value change mode).
