Power 7 V2.0c Cyclic Charging Supplementary Instructions
The V2.0c version of the Power 7 Controller recognizes the incoming supply voltage frequency on power up and if it detects a frequency of 60Hz,
(the frequency of a 110v/120v supply) as typically used in Northern and Southern American countries such as Canada and the USA etc, it will switch
the controller into Cyclic Charging Mode.
When the Power 7 is initially powered up it will display the "Line Freq =" followed by the measured line frequency e.g. in the case of Canada "60 Hz"
If a frequency of 60Hz is detected on power up then Mode One is selected. This mode switches 3 of the 4 powerstrips on initially and then cycles
the power strips on a 3 on/1 off cycle every 15 mins as per the chart below:
Sequence
Time
15mins

Repeat
The Sequence mode can be changed from Mode 1 – 3 on/1 off to an alternative Mode:
Mode 2 – 2 On/2 Off as per the Sequence Chart below:

Repeat
In addition to changing the sequence mode, the Time Delay for each sequence change can also be changed from 10 to 60 mins.
Changing the Sequence Mode and Time Delay
Sequence Mode
To change the sequencing mode and/or sequence time delay, switch off the power to the charging cart, then press and hold the left Power 7
button (the '-' button) and switch on the supply to the charging cart . "Sequence Mode" will be displayed on the top line of the Power 7
Display.
On release of the left hand '-' button, the sequence option screen is displayed – Options are:
"None One Two"
Sequence None puts the Power 7 into a none sequencing mode i.e. all powerstrips will be switched on all the time when in a charging mode.
Sequence "One" and "Two" are as previously described.
To Change the sequence mode simply press the respective button below the display.
If no selection is made within 10 seconds, the Power 7 will go into Auto Mode and hence switch to Sequence One if it detects a 110v/120v/60Hz
supply or "None" mode if it detects 230v/240v/50Hz supply.
Pressing "None" will put the power 7 into a none sequencing mode i.e. all powerstrips will be switched on.
Pressing "One" will put the power 7 into a 3 On/One off sequencing mode
Pressing "Two" will put the power 7 into a 2 On/2 Off sequencing mode
