11. Trip Point Setting
You can set trip points using the rotary switches on the front panel.
Refer to the table below and set the trip points by turning the rotary
switches with a screwdriver or the like.
Notes:
- The setting must be done with power off.
- Special care should be taken to avoid placing the rotary switch
halfway between dial indicator positions. Turn the switch until it
clicks into place and is firmly seated.
(Example)
When, with an input range of 0-5V, you want to set the trip points
for OUTPUT1 and OUTPUT2 to 4V and 2.25V, respectively, set
the rotary switches as follows:
Since 4V is 80% of the input span (5V), set the RY1-SET×10
switch to 8 and the RY1-SET×1 to 0.
Since 2.25V is 45% of the input span (5V), set the RY2-SET×10
switch to 4 and the RY2-SET×1 to 5.
