However, if a power failure lasts for long, or the power voltage decreases, TP04P will
stop running, and all outputs will be off. After the power returns to the normal status,
TP04P will automatically resume the operation. (Users have to note that TP04P is
equipped with latched auxiliary relays and registers when they write a program.)
Safety Wiring
Since TP04P is only compatible with DC power supply, Delta’s power supply modules
(DVPPS01/DVPPS02) are suitable for it.
İ
t is suggested that you shoudl install a
protection circuit at the power supply terminal to protect DVPPS01 or DVPPS02. See
the figure below.
