8.1
System Volts
On initialisation, if the battery voltage is not within one of the ranges for the systems as shown in Table I, the Battery Volts LED will flash and the piezo buzzer will sound. The display will show the actual voltage measured. The program will continue to measure the battery voltage and test to see if it is within range. [fit detects the voltage within range it will display the system voltage selected and remove the alarm condition. [f the batteries have been float charged before the Semmar II was connected the battery voltage may be higher than I 00% value. A small load across the battery will reduce the battery voltage enough to allow the system to initialise correctly.
8.2
Low Battery
If the battery voltage drops below the Low Battery On value stated in Table I the Low battery indicator will come up on the LCD display and the LED will light. The piezo buzzer will sound at the same time. The Scroll Button can be used to cancel the piezo buzzer. The Low Battery con.dition will continue to display until the battery reaches the Low Battery Off value. At th.is point the display will be cancelled and the alarm reset.
8.3 Solar Panel Fault
After Start of Day or 8 am (08 H), and before 4pm {16 H) the Seminar II will constantly check the Solar Current (when the relay is closed) and the Solar Voltage (when the relay is open). If the Solar Current falls to zero or negative for more than two seconds the relay will be opened. The Solar Voltage will then be checked. If the Solar Voltage is less than 1 Volt, for more than 3 seconds, the Solar Panel Alarm will sound and the Solar Current and Voltage LED's will flash. The Scroll Button can be used to cancel the piezo buzzer. The Solar Current and Voltage LED's will continue to flash until the Solar Voltage rises above 1 Volt (the panel is reconnected). The alarm will automatically reset and regulation will continue.
8.4 Temperature Probe Fault
lfthe Temperature Probe is selected (P02) and there is no value read by the microprocessor (00.0 displayed), the probe is assumed to be faulty or disconnected. An alarm will sound ( one long and two short followed by a long pause) and the Battery Volts LED will flash. This indicates that the Seminar II regulator has detected a Temperature Probe Fault and is regulating the battery voltage around the nominal 20 °C Float and Boost values. The Scroll Button can be used to cancel the piezo buzzer and the flashing LED. The Seminar II will continue to regulate around the nominal values until a valid temperature reading is received. When th.is happens the Temperature Probe alarm will automatically be reset.

2.2.1
Beginning of Day
At first light of day the charge cycle starts with the detection of voltage from the solar array. When the voltage from the solar array rises to the Battery Voltage, the charge relay is closed and the solar array is connected to the battery bank. An Automatic Boost Cycle is commenced and continues for 20 minutes after the Battery has reached Boost Stop Voltage. During the Automatic Boost Cycle the battery is charged to the "Boost Stop" voltage and maintained at this value. The 20 minute "Boost Cycle" period provides for battery cell equalisation.
Seminar// Version 1

W INDPOWER AUSTRALIA
The Seminar II regulator will automatically check the time of day and display an alarm if the solar voltage does not rise above the battery voltage after Sam. The piezo buzzer will sound and the Solar Volts and Solar Current LED's will flash. Pressing the SCROLL button will reset the alarm. The alarm will sound again after 5 seconds if solar voltage is not detected.
2.2.2
During tbe Day
When the battery voltage falls below the "Float Voltage" value the relay is closed after a delay of 8 seconds. The solar panel charges the battery until the "Float Voltage" value is reached and the relay is opened after 2 seconds. The eight second OFF, 2 second ON delay ensures that the charge relay does not continuously open and close as the battery is charged and discharged under heavy loads. The delay also prevents transients from accidentally turning the relay off and on. The Seminar II regulator will automatically check the solar voltage and current from Start of Day to 4pm If the solar voltage drops below the battery voltage or the solar current falls to zero, for 5 seconds, the piezo buzzer will sound and the Solar Volts and Solar Current LED's will flash. Pressing the SCROLL button will reset the alarm. The alarm will sound again after 5 seconds if solar voltage or current is not detected.
2.2.3
Finish of Day
At the Finish of Day, after 4 pm, when there is no solar current flow to the battery from the solar panel for more than 10 seconds, the Charge cycle is stopped. The charge relay is opened and the Solar Voltage is monitored until first light. If the solar voltage rises above the battery voltage the relay will close after eight seconds and the regulator will go back into Daylight mode, regulating around the float voltage. The real time clock is used to keep track of each days readings. It will produce an End of Day and begin a new "DAY" at midnight.
2.3
Manual Boost
The manual boost facility allows the user to provide a boost charge for the battery at any time.
2.3.1
Boost Charge
When the BOOST button is pressed the Seminar II system will automatically charge the battery to the Boost Stop voltage before opening the relay.
Seminar// Version 1

2.3.2
Boost Cycle
Eight seconds after the Battery voltage falls below the Boost Stop voltage the charge relay will close and the solar panel will charge the battery up to Boost Stop voltage. This boost cycle will continue until the BOOST button is pressed again. Ifthe Boost cycle is in operation at the End OfDay it will automatically be reset.
