Can more than one remote control be paired to a single receiver?
How many transmitters can be paired to a receiver depends on the set's learning logic, and no number is stated in the product data. So if you are planning a spare remote control or two-operator use, confirm the capacity from the user manual or technical support before purchase. Functionally, the correct arrangement is for only one operator to give commands at a time.
Technically more than one transmitter identity can be stored in a receiver's memory; this is a common need for keeping a spare remote control or using two separate units across two shifts. However, how many remote controls can be paired is not stated in the product data; verify this value from the manual or technical support.
On the operational side there is a more important point to watch: two people being able to command the same machine at the same time is risky from a safety standpoint. Good practice is as follows:
- Only one remote control should be in use at a time; the other should sit as a spare in a locked cabinet, switched off.
- Handover of the remote control at shift change should be recorded.
- Each remote control should clearly state which machine it belongs to.
- The wired emergency stop circuit on the machine must be accessible under all conditions.
After the spare remote control is paired, test all channels without a load connected and then carry out a verification under load. The spare unit's battery must also be charged periodically or its cells checked; leaking cells in an unused device are a common failure.
