7. Resume Function/ EPC System Monitor
Resume Function
Resume function can keep PT-E operating regardless of the occurrence of instantaneous interruption or
power failure and protect data by equipping a lithium ion battery pack (option) on PT-E. With EPC
System Monitor, it is possible to choose [Continue mode] or [Standby mode] when power failure
occurring and do time setting. Moreover, when battery voltage drop is detected or power supply is not
restored after power failure, PT-E will go to shutdown automatically.
(1) Continue mode
a. When power failure is detected, PT-E keeps on operating, but backlight becomes OFF. (In
Continue mode, screen operation is unavailable.)
b. If power supply restores before passing the setting time (0 to 10 minutes), or power supply restores
before detecting battery voltage drop, backlight will become ON, and operation goes on.
If power supply does not restore, goes to shutdown (*1).
c. If battery voltage drop is detected before passing setting time, PT-E goes to shutdown (*1).
(*1): You can set whether execute shutdown process or not. (Refer to p. 78.)
(2) Standby mode
a. When power failure is detected, backlight becomes OFF, PT-E goes to standby state.
b. If power supply restores before passing the setting time (0 to 30 minutes), or power supply restores
before detecting battery voltage drop, standby state is released, and PT-E restarts operation from
the state right before power failure. If power supply does not restore, PT-E goes to shutdown.
c. If battery voltage drop is detected before passing setting time, PT-E goes to shutdown.
Point
(1) For using resume function, you must equip a lithium ion battery pack with PT-E.
(2) Before using resume function, always fully charges the lithium ion battery pack. (Continuously
charge the battery pack for eight hours and confirm [Charge end] by EPC System Monitor.)
(3) For using resume function, you must start software EPC System Monitor and do necessary settings.
(Refer to next page)
(4) Use EPC System Monitor to set operation time of [Continue mode] or [Standby mode].
(Refer to p. 73.)
CAUTION
- In case of connecting external devices, if you are using resume function, the currents supplied to the
external devices should be under DC5V/1A.
- If connects external devices that supplying current more than DC5V/1A, over current detection of
lithium ion battery will work, so that Continue mode and Standby mode can not work normally. In
this case recommend using an external UPS.
- If lithium ion battery is not full-charged, PT-E might go to shutdown operation even within the
specified time.
- If lithium ion battery is in the state of discharge (under 6.7V), resume function will not work.
