CHECKING
1) Terminal wiring: Check that all cables are correctly
connected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal 7
– 8 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
4) Output
• Open collector: Check that the output load is 30V DC/
30mA at the maximum. Saturation voltage is 1.1V DC.
Check the input threshold voltage (at L level) of the
connected device to be greater than that.
• CMOS level: Check the output voltage. (H
≥
4.5V DC, L
≤
0.5V DC)
LIGHTNING PROTECTION
In order to protect the unit from lightning surges entering
through power supply cables, use of appropriate lightning
surge protectors are recommended. Please contact M-Sys-
tem.
