JUMPER SETTINGS
4 kΩ is attached for open collector and mechanical contact
input, while 200 Ω, 510 Ω or 1 kΩ is attached for two-wire
current pulse input.
Resistance can be changed by modifying jumper combina-
tions as shown in the table below.

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage supplied to the rack
(model: 18BXx or 18KBXx). For the DC power source, be
sure that the ripple level is within 10% p-p.
3) Input: For the mechanical contact input, check that the
input frequency is 5 Hz or less and the pulse width is 20
msec. or more.
For the open collector input, check that the input fre-
quency is 10 kHz or less and the pulse width is 20 μsec.
or more.
For the voltage pulse input or two-wire current pulse in-
put, be sure that the input signal is as shown in the table
below.

Check also that the output current is 100 mA or less at
ON, 0 mA at OFF.
