Chapter 1 Before Starting Operation

Principles of Operation
Process variable (input) signal of the YS instrument with MV output is input to the YS110
via a cable by plugging its cable into a connector on the case of the YS instrument with
MV output. Then, it is applied to a high input resistance (RIN), input filter (R and C), buffer
amplifier(U1) and switch. The level of the signal can be indicated on the input indicator.
The voltage level of the internal batteries can also be indicated on this input indicator by
pressing the battery check push button.
For the manipulated variable, the value set by the manual operation wheel is applied to
Q1viathebufferamplifier(U2), and converted from a voltage value to a current value.
Then, it is output from the output terminals on the case, via the manipulated variable
indicator and the switch, to the control valve actuator.

1.3 Battery Voltage Level Check
CAUTION
If you use the YS110 with insufficient battery level, the backup operation may be
interrupted.

battery as necessary.
Procedure
1. Set the selector switch to SET.
2. Operate the manual operation wheel to set 100% on manipulated variable indicator.
3. Press the battery check push button.
While the battery check push button is held down, the input indicator shows the
battery voltage level.
When the level is 100 to 75%: The YS110 can be used.
(The YS110 will operate continuously for 10 minutes
when the level indication is 75%.)
When the level is less than 75%: Replace the batteries before starting operation.
