Summary
The eMAX system is equipped with an intuitive alarms menu that allows users to set up two essential types of weight-based alarms: Overload alarms and Differential alarms. These alarms enhance safety and efficiency during lifting operations by providing timely alerts. It's only aplicable with load cell installed hooks.
Alarm Types and Functions
- Overload (Warning + Value): This alarm triggers when the weight on a single hook exceeds a predetermined limit, ensuring that the load does not surpass the safe operating capacity.
- Differential + Value: This alarm activates when the weight difference between two hooks exceeds a specified threshold, which is particularly useful in tandem lifting scenarios.
Accessing the Alarms Menu
To configure these alarms, follow these steps on your eMAX device:
1. Navigate to SETTINGS.
2. Select eMAX.
3. Go to SCALE and then **ALARMS**.
In this menu, you will find several options to customize your alarm settings:
- Reset alarms: This option disables all active alarms, allowing you to clear the alarm status before starting a new lift.
- Warning: Toggle this setting to enable or disable the overload alarm.
- Value: Here, you can set the weight threshold for the overload alarm.
- Differential: This option enables or disables the differential alarm.
- Value (under Differential): Set the maximum allowed weight difference between two hooks.
Alarm Type 1: Overload Alarm (Single Hook)
This alarm can be set when lifting with a single hook with loadcell installed.
Configuration Steps:
- Warning: Set to **ON** to activate the alarm.
- Value: Enter your desired weight limit in kg or lbs.
Behavior:
When the load exceeds the set Value, the eMAX screen will display a warning, emit an audible beep, and the hook will continue normal operation, as the alarm serves as an informational alert.
Example: For an EVO5 with a 5000 kg capacity, if you set Warning to ON and Value to 4500 kg, the alarm will trigger when the load exceeds 4500 kg.
Alarm Type 2: Differential Alarm (Two Hooks, Tandem Lifting)
This alarm can be set for lifting loads with two hooks, especially for long or unbalanced loads.
Functionality:
The differential alarm monitors the weight difference between Hook A and Hook B. If this difference surpasses the configured Value, the alarm will trigger, preventing load shifting and ensuring balanced lifting.
Configuration Steps:
- Differential: Auto set **ON**.
- Value (under Differential): Enter the maximum allowed weight difference in kg or lbs.
Example: If two hooks are lifting a 10,000 kg beam and you set the Differential to ON with a Value of 2000 kg, the alarm will trigger if Hook A reads 7000 kg and Hook B reads 3000 kg (4000 kg difference, which exceeds 2000 kg).
Resetting Alarms
To disable an active alarm after it has triggered or to clear the alarm status before initiating a new lift, use the **Reset alarms** option. This action does not alter your configured settings for Warning, Value, or Differential; it simply resets the active alarm state.

Summary Table
| I want to... | Settings to use |
|---|---|
| Get an alarm when a single hook exceeds X kg | Warning = ON, Value = X |
| Get an alarm when two hooks are unbalanced | Differential = ON, Value = X (max difference) |
| Turn off a triggered alarm | Reset alarms |
| Disable all alarms | Warning = OFF, Differential = OFF |
By following these guidelines, you can effectively configure and manage overload and differential alarms on your eMAX system, ensuring safe and efficient lifting operations. If you have any further questions or need assistance, feel free to reach out to our support team!
