1.5.3-9 Input for remote control signals
These connection terminals enter actions corresponding to the run-state operation
keys of the IJ printer (Run, Stop, fault Clear, and Deflection Voltage Control
(switchover between a standby state and a ready state), by means of external switches,
contact signals, or something similar.
(a) Input specifications
Make inputs by no-voltage contacts.
・
In the case of no-contact, use terminals that satisfy the following requirements:
・
Withstanding voltage: 12 VDC or more
Maximum driving current: 12 mA or more
Residual voltage: 2 V or less
Leak current: 0.1 mA or less
Driving method: Open collector
In the case of contact signal
・
In the case of the chattering when contact is ON or OFF , use terminals of 2.0
ms or less.
(No-voltage contact)
The current applied to the
system is about
12 mA.
When all input contacts are ON, the system runs in the same manner as when the
