Power On/Off
WARNING
Electric shock
Do not touch electrically charged parts.
Doing so may cause electric shock.
IMPORTANT!!
•
Do not test the withstand voltage of this product.
Doing so may cause the device to fail.
•
If more than the rated power voltage is applied to this product, replace the product with a new one.
Failure to do so may result in a malfunction.
In order to retain the minimum required system data, the product has an on-board lithium ion capacitor module.
When no power is supplied due to power failure or power shutoff, the lithium ion capacitor module supplies power for one
second (by default) to maintain functions excluding direct inputs/outputs as a countermeasure against instantaneous power
failure. It then continues supplying power until the status data stored in the memory is transferred to the secondary storage
medium (SSD) as part of the shutdown process.
When power is supplied from the main power supply due to restoration of power or power-on operation, the module is
charged automatically.
•
Charge the lithium ion capacitor module by turning on the power for the product within six months of its delivery.
Turning on the power charges the capacitor automatically.
A continuous charge duration of five minutes or less is required for a full charge.
•
If a fully charged lithium ion capacitor module has been off for six months or more, it will have fallen below the discharge
stop voltage (6.9 V). Charging the module in this state significantly reduces the part life.
Therefore, if an excessively discharged state is detected, this product stops charging the lithium ion capacitor module
for the sake of safety. The lithium ion capacitor module will no longer be able to be charged.
If the POWER LED does not stop flashing and stays on for 10 minutes after turning the power on when the controller is
already charged, the controller itself must be replaced.
•
Do not turn the power on/off frequently.
After it is turned on, wait at least 5 minutes before turning it off.
•
If the SVC will not be turned on again for one month or longer, turn it off in shutdown mode.
z
Turning OFF the SVC
(1) Press the [>] button (one of the user operation switches) three times at intervals of less than 1 second.
The shutdown mode will be activated and “
” will be displayed.
Note: If the interval is 1 second or longer, the mode will return to automatic mode.
(2) Press the [ENTER] button.
When the shutdown process is complete, “
” will be displayed.
The LEDs and system indicators will be turned off.
Note:
1. Pressing any button except [ENTER] will return the unit to automatic mode. Also, if no button is pressed for 5
seconds or longer, automatic mode will resume.
2. “
” will flash every second while shutdown is in process.
(3) Turn off the power to the SVC.
