The settings for the dip switches show five as in off off on on on but the meter in the R30 that I **** working on has seven switches. What’s the difference and or the correct settings for 4 6 volt discover batteries?

To determine the correct dip switch settings for the Hillyard R30SC when using four 6-volt Discover batteries, we need to calculate the total system voltage and find the appropriate battery type and voltage threshold settings from the manual.

### Step 1: Determine System Voltage
- Four 6-volt batteries connected in series result in a total voltage of 24 volts (6V × 4 = 24V).

### Step 2: Set DP1 and DP2 for System Voltage
From the manual:
- 24V system → DP1 = OFF, DP2 = ON

### Step 3: Identify Battery Type
Discover 6V batteries are most commonly sealed AGM or GEL batteries. Depending on the specific model of Discover battery, they could fall under:
- GEL+ / AGM+ (Gel80)
- GEL / AGM (Gel60)

You will need to confirm which type your Discover batteries are, but assuming GEL / AGM (Gel60) (a common configuration), we use the corresponding threshold voltage settings.

### Step 4: Set DP3–DP6 for GEL / AGM (Gel60)
From the manual:
- GEL / AGM (Gel60) options:
- 21.8V → DP3 = ON, DP4 = OFF, DP5 = OFF, DP6 = OFF
- 22.0V → ON, OFF, OFF, ON
- 22.2V → ON, OFF, ON, OFF
- 22.4V → ON, OFF, ON, ON
- 22.6V → ON, ON, OFF, OFF
- 22.8V → ON, ON, OFF, ON

Choose the threshold based on how deeply you want to discharge the battery before the system signals low voltage. A common setting is 22.0V.

So for 22.0V threshold (GEL / AGM):
- DP3 = ON, DP4 = OFF, DP5 = OFF, DP6 = ON

---

### ✅ Final Dip Switch Settings for Four 6V Discover Batteries (24V GEL / AGM, 22.0V threshold):
- DP1 = OFF
- DP2 = ON
- DP3 = ON
- DP4 = OFF
- DP5 = OFF
- **DP
