On the Bullhorn RM510C and RM510S, use Channel 1 for rectifier amps and Channel 2 for rectifier volts. Bullhorn Web reads analog Channel 1 as amps and Channel 2 as volts.
Applies to: Bullhorn RM510C, Bullhorn RM510S (RM5 series)
| Channel | Use it for | Set in FieldPro |
|---|---|---|
| Channel 1 | Rectifier current (amps), read across the shunt | Shunt Rating (mV) and Current Capacity (A), for example 50 mV / 100 A |
| Channel 2 | Rectifier voltage (volts), up to ±150 V DC or 150 V AC | Input Type and Range |
Note: Before you start, have these ready:
- FieldPro, connected to the unit by Bluetooth
- The site's shunt rating and current capacity
- A DVM, to check the readings
Steps
-
In FieldPro, tap Channels & Alarms.
You should see: the list of channels.
-
Select Channel 1 (amps). Set the Shunt Rating (mV) and Current Capacity (A), for example 50 mV / 100 A.
You should see: Channel 1 set to read amps.
-
Select Channel 2 (volts). Set the Input Type and Range for the rectifier voltage.
You should see: Channel 2 set to read volts.
-
Tap Save & Send Configuration, then Send Test Message.
You should see: the settings saved to the unit and a test packet sent.
-
In Bullhorn Web, open the unit's Packets tab. Compare Channel 1 (amps) and Channel 2 (volts) with your DVM readings.
You should see: readings that match your DVM within ±1%.
If It Didn't Work
| What you see | What it means | What to do |
|---|---|---|
| Amps show on Channel 2, or volts on Channel 1 | The leads or the channel settings are swapped | Put amps on Channel 1 and volts on Channel 2, then send a new test message |
| The amps reading is far off | The shunt rating or current capacity is wrong | Check both against the shunt's label, then save again |
