<Caution>
• Input the signals to the Lossnay (SW5-10 ON, with the smallest address setting) set as the main Lossnay in
the group.
(Note 1) The input signal must conform to the following specifications:
Level signal
Pulse signal
In the case of relay contact input, use a relay having a contact rating of 15 V DC/0.1 A or higher and a
minimum applicable load of 1 mA or less.
(Note 2) Check the specifications of the external device.
