CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected 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 frequency is 30 Hz or less
for relay contact, 100 kHz or less for other types of input.
Check also that input pulse is 10 msec. or wider for relay
contact, 5 µsec. or wider for other types of input.
4) Output: Check that the load resistance meets the de-
scribed specifications as shown below.
