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.

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.
