●Timing chart
t1: Time from the point where the indicated value exceeds the HI limit setting value to the point
where PhotoMOS relay is ON.
t2: Time from the point where the indicated value falls to the HI limit setting value or below
the point where PhotoMOS relay is OFF.
■HI limit / LO limit / HH limit / LL limit setting method
1.
Select setting mode 1.
2. Set "HI limit".
Press the key once.
Set the HI limit value using the
(numerical value input) and (shift) keys, and
confirm it with the key.
Press the key to insert a minus sign.
3. Set "LO limit".
Press the key once.
Set the LO limit value using the
(numerical value input) and (shift) keys, and
confirm it with the key.
Press the key to insert a minus sign.

e.g.) HI/LO limit comparison mode: Ongoing comparison
Hysteresis: 0
* Only HI output is indicated. Likewise with other signals.
t1 t2
t1, t2: Approx. 1mS
Hysteresis can be set in order to prevent chattering of PhotoMOS relay.
Refer to P.48 “6-4.Hysteresis” for details.
