ATEX
Equipment for explosive atmospheres
LRC Small/Remote is described for use in Ex Zone 1 and uses an ATEX-tested battery pack. Amplifiers and chargers are installed outside the Ex zone in a protected area.
Keep loading and unloading under control, even with single-operator workflows
Wireless dead-man timers and emergency stop functions for tanker trucks, depots, and mobile operations.
LRC and LRC3 combine dead-man acknowledgements with remote control for pumps and valves. If acknowledgement is missed, the operation is automatically brought to a safe stop.
Implement a dead-man workflow with configurable acknowledgement intervals. On timeout, radio loss, or fault conditions, the system brings the operation to a safe stop.
30 s, 1, 2, 4 minCommon dead-man intervals
Other intervals are possible depending on application and configuration.
up to 300 mRadio range (typical)
Depends on environment, installation, and radio conditions.
Transfer points need immediate stop capability
During loading and unloading, operators must watch product flow, valves, and surroundings at the same time. In practice there is often a trade-off between visibility at the connection point and maintaining a safe distance.
Without dead-man logic, risk rises during human error and technical failures
Missed confirmation, distraction, or radio and system faults can allow an operation to continue longer than intended. This increases the risk of overfill, leaks, and unplanned downtime.
A defined workflow and a defined stop
Dead-man intervals enforce regular operator interaction. At the same time, emergency stop and remote control functions for pumps and valves allow the operator to run the operation from a suitable position.
How the LRC dead-man workflow operates
The system guides the operator through a clear workflow with timer, warning, and safe stop.
- 1
Start and timer
After enabling the operation, the dead-man timer counts down visibly and must be acknowledged in time.
- 2
Warning and safe stop
Before timeout, an audible or visual warning is issued. If acknowledgement is not provided, the system stops the operation automatically.
- 3
Remote control functions
Depending on configuration, functions such as pump start, pump stop, speed control, fill stop, and emergency stop are available. Ex-rated components and placement of amplifiers are designed according to the site zoning concept.

Proof & success stories
Key metrics
- Examples of dead-man intervals
- 30 s, 1 min, 2 min, 4 min
- Warning logic (example)
- 20 s + 10 s
Dead-man time is configurable. Common settings include 30 seconds and 1, 2, or 4 minutes.
Example described: after 20 seconds a warning is issued, and after a further 10 seconds the system stops if no acknowledgement is given.
Plan your dead-man and emergency stop integration
We help select Ex or non-Ex components, integrate with pump and valve circuits, and configure dead-man timing for your application.
