Fukuda FL-286 - Remote Terminal Board and Signals; Control Signal Definitions; Cylinder and Group Control Signals

ELECTRIC WIRING CONFIGURATION
Control testing and bubble testing procedures
・ START Start of air leak test.
Applies a pulse signal of 0.5 sec or longer during DLY sequence.
・BUBL Start of bubble test
Performs a bubble test while a signal is being applied.
・RESET Stop the tester in case of an emergency.
Apply a break signal to open the air circuit. The RDY sequence
is established after EXH sequence.
Test result output
・OK -NG set range ＜ leak reange ＜ +NG set range
・+NG leak reange ≧ +NG set range
・-NG -NG set range ≧ leak reange
・P.NG Test pressure is lower than the set value at the end of
PRES sequence.
・P.NG Test pressure is lower than the set value set up with
P.SW at time of BAL sequence.
Current status output
・RDY Standby (Ready Status)
・ERR Error has transpired.
When the power is OFF, ERR can be used to confirm
ON/OFF status.
・END Testing has ended.
＊1 The air leak tester’s internal output status: power off.
＊2 The names, indicated with line（＊＊＊）imply that the signal is effective when it is open. 19
Controlling clamping cylinders
・LMT 1 Input of unclamp signals
・LMT 2 Input of clamp signals
・SOL 1 Cylinder Driving valve control signals
※
In the Internal Operation Mode, the tester cannot operate.
