Howdy all,
I recently added a freewave radio to one of my sites. We use SW12V to preserve battery life by turing the radio on for only 5 minutes per hour.
The problem is, this site has a new HMP45C that also runs off of switched 12V. The program for the HMP45 uses a CP to turn the SW12V on and off. I decided to put that first, and follow it with my standard radio program, which I thought would turn it back on. However, I can only connect to this radio (with the flag on) at 5-10 minutes after the hour, rather than 0-5 minutes after. This setup also leaves the HMP for long periods. (Note: this is in a dark corner of AK so battery life must be conserved in the winter)
Does anyone have suggestions for dealing with this problem? I thought maybe a delay was needed between the HMP and the radio controls. I just tried that remotely, not sure if it will work for another hour though.
Brian
Existing program (without delay):
1: Batt Voltage (P10)
1: 1 Loc [ BatteryVoltage ]
; put hmp sw12V control before radio so it won't turn radio off right away.
2: Do (P86)
1: 41 Set Port 1 High
3: Excitation with Delay (P22)
1: 1 Ex Channel
2: 0 Delay W/Ex (0.01 sec units)
3: 15 Delay After Ex (0.01 sec units)
4: 0 mV Excitation
4: Volt (SE) (P1)
1: 1 Reps
2: 25 2500 mV 60 Hz Rejection Range
3: 2 SE Channel
4: 3 Loc [ AirTemp_150cm ]
5: .1 Multiplier
6: -40 Offset
5: Volt (SE) (P1)
1: 1 Reps
2: 25 2500 mV 60 Hz Rejection Range
3: 3 SE Channel
4: 4 Loc [ RelHum_150cm ]
5: .1 Multiplier
6: 0.0 Offset
6: Do (P86)
1: 51 Set Port 1 Low
;------------------------------------------
;Put radio stuff here
7: Set Port(s) (P20)
1: 7999 C8..C5 = output/nc/nc/nc
2: 9999 C4..C1 = nc/nc/nc/nc
8: If time is (P92)
1: 0 Seconds into a
2: 3600 Second interval
3: 30 Then Do
9: If (X<=>F) (P89)
1: 1 X Loc [ BatteryVoltage ]
2: 4 <
3: 12 F
4: 21 Set Flag 1 Low
10: If (X<=>F) (P89)
1: 1 X Loc [ BatteryVoltage ]
2: 3 >=
3: 12 F
4: 48 Set Port 8 High
11: End (P95)
12: If time is (P92)
1: 28800 Seconds into a
2: 86400 Second interval
3: 48 Set Port 8 High
13: If Flag/Port (P91)
1: 21 Do if Flag 1 is Low
2: 30 Then Do
14: If time is (P92)
1: 300 Seconds into a
2: 3600 Second interval
3: 58 Set Port 8 Low
15: End (P95)
Since no one has responded, I have asked one of our application engineers to look at your question and try to help you. Hopefully he will be of assistance.
You can purchase another SW12V, 12V Power Switch to run your freewave radio. The SW12V is P/N 17408.
Brian,
I have a basic question. Do you just turn on the HMP45C Once per hour to take a reading?
Thanks,
IslandMan
Craig,
What is this 17408 part number item you refer to? it is not in the ecatalog. Brian could use the part number 7321 crydom D1D07 relay to accomplish what he needs.
We need to turn on a CR10X SW12 output with the following condition:
If Hour > 6 AND Hour < 17 Then
If VoltPanel > VoltPanelMin Then
If blnFallaPanel = 1 Then blnAlerta = 1
blnFallaPanel = 0
Else
If blnFallaPanel = 0 Then blnAlerta = 1
blnFallaPanel = 1
EndIf
SW12(0)
Else
If blnFallaPanel = 1 Then blnAlerta = 1
blnFallaPanel = 0
SW12(1)
EndIf
The condition described works for a CR850, can help us telling how we make it work for a CR10X?
Or how can we to activated the SW12 between 17:00 at 05:00
