97Power Board Displays the part number and revision of the power/relay boardSensor Board #1 - #4 Displays the part number and revision of the I/O boards (One entry for each boardinstalled, up to 4)Software Version Displays the software version on each I/O board (One entry for each board installed,up to 4)Last Data Log Displays the date and time of the last data log downloadDigital Inputs Displays the part number and revision of the digital inputsSoftware Version Displays the software version of the digital inputsNetwork Displays the part number and revision of the network circuitSoftware Version Displays the software version on the network circuitBattery Power Displays the VDC output of the battery that is used to hold the date and time. The accept-able range is 2.4-3.3 VDC.Controller Temp 1 Displays the temperature of the first controller thermistor. The acceptable range is -10to 75 C.Controller Temp 2 Displays the temperature of the second controller thermistor. The ac-ceptable range is-10 to 75 C.Relay Board Temp Displays the temperature of the relay board thermistor. The acceptable range is -10 to 75 C.Processor Temp Displays the temperature of the controller board processor. The acceptable range is -10to 75 C.DI Temp Displays the temperature of the digital input processor. The acceptable range is -10 to75 C.I/O Card 1-4 Temp Displays the temperature of each I/O module processor. The acceptable range is -10 to75 C.Network Temp Displays the temperature of the network circuit processor. The acceptable range is -10to 85 C.+12 Volt Supply The normal range is 11.28 to 12.72 VDC. The 12 V supply is the main DC power fromwhich all lower voltages are generated.+5 Volt Supply The normal range is 4.7 to 5.3 VDC. The 5 V supply is used for powering all the I/O.+3.3 Volt Supply The normal range is 2.8 to 3.5 VDC. The 3V supply is used to run the system.LCD Bias Voltage The normal range is -25 to -20 VDC. This is the touchscreen voltage after contrast adjust-ment.LCD Supply The normal range is -25 to -20 VDC. This is the touchscreen voltage before contrastadjustment.5.5 HOA MenuThe HOA (Hand-Off-Automatic) Menu is used to quickly and easily test all relay outputs, and to stop or enable auto-matic control.Touch the relay number in order to change the HOA state of that relay. The relay number will be shaded dark, andits current HOA state will be shaded dark. Then touch the desired state. The change happens immediately unless thatrelay has a Minimum Relay Cycle programmed that is above 0 seconds.5.6 Graph MenuThe Graph Menu is used to display a graph containing one sensor or analog input value plus one digital input or relaystate. Touch the Graph icon and the controller will display “Generating Graph Please Stand By” for a few seconds thenshow the graph. The default is to show the value of sensor input S11 and the state of relay output R1 over the past 10minutes.Touching any point on either line on the graphs displays a vertical line plus the details for that data point: date andtime, value of the sensor, and an arrow showing if the state or the digital input/relay was high or low at that time.
