1-30 Connection of signals
1.5.3-3 Warning signal output
The following describes the wiring of the signal that is outputted to the outside for the
purpose of indicating that the IJ printer is in the warning mode.
(a) When using the NO contact (make contact)
Status indicator
lamp or the like
Power supply
TB2
8-9 contact
Warning state Closed
Normal state Open
(b) When using the NC contact (break contact)
Status indicator
lamp or the like
Power supply
TB2
7-9 contact
Warning state Open
Normal state Closed
For both the NO and NC contacts, the maximum capacities of the fault and warning
condition outputs are 30 VAC/0.5A, or 30 VDC/1 A. If any load having a greater
capacity is used, furnish a separate relay in between.
Further, if a motor, relay, or other inductive load is employed, a counterelectromotive
force may be generated to reduce the useful contact life.
Therefore, be sure to provide contact protection as suggested for the ready output
signal wiring.
