Which are the advantages of the digital Master-Slave function?
With these models the switching threshold can be set up automatically via the push of a button. If you dont require the master-slave function at the moment, you can activate the permanent mode for the slave sockets if desired. The power strip will then ignore the master-slave function. The stored switching threshold, or rather the permanent mode, will also remain if the master-slave power strip is temporarily turned off by the main switch.
Why does my automatic outlet strip no longer shut off the slave outlets?
Some customers have the problem that the slave outlets are no longer shut off although the master unit is switched off. The causes for this can be very high switch-on currents of the slave units which severely exceed the max. load of the relays and thus fuse the switch contacts. In many cases, the switch contacts can be separated by vibration (knocking) and will then work temporarily. However, the problem will generally return if the configuration of the slave units is not changed.
Our automatic outlet strips overall and the relays used therein are designed for a constant load with currents of 16A. End devices with a safety outlet cannot handle more than that. However, some end devices exceed this threshold value by a significant amount when switching on. The current consumption can increase to 50A or more for a fraction of a second. These high currents can result in the switch contacts fusing so the relay no longer switches off. In our experience, the problem occurs more frequently with end devices with switch-based power supply units. These can be installed nearly anywhere these days, e.g. PC, monitor, printer, external hard drives, active speakers, etc. Which products concretely cause such problems also depends on whether or not the manufacturer of the end devices has implemented corresponding measures against the switch-on currents being too high. This cannot, unfortunately, be found in the data sheet or on the type plate. We have optimized our automatic outlet strips by installing special relays for impulse loads of up to 80A. This has resulted in the problem arising less frequently.
What can I use an automatic Master-Slave power strip for?
The power switch of a single device plugged into the master socket will automatically shut on and off all other devices plugged into the slave sockets. For example, you can use a computer as a master device, and a printer, monitor, modem and so on as slave devices incorporated into the automatic control. Of course you can also use such combinations as TV, radio, receiver, and so on.
How do I set up the switching threshold at an automatic power strip with control?
1. Place your master device in the master socket and switch it on. 2. Slowly and carefully turn the control of the switching threshold until you find a position in which the slave socket will be turned on and off. Note this as control position 1. (for users with higher power consumption leave the slave socket on). 3. Turn the master device off again, but let it remain plugged in. 4. Slowly and carefully turn the control of the switch until you find a position in which the slave socket will be truned on and off. Note this as control position 2. (for users with or without lower standby-power consumption the slave sockets stay turned on at all times). 5. Adjust the control in the centre between control position 1 and control position 2. (if you cannot find control position one or two adjust the control in the centre between the controller stops).
How do I set up the switching threshold on an automatic power strip with a digital master-slave function?
These devices feature an automatic switching threshold setting, which is activated by pressing a button: 1. Turn on the automatic power strip at the main switch. 2. Insert the master device into the master socket. 3. Switch the master device into the standby mode or turn it off completely, if it is not already. 4. Press and hold the button Learn” on the automatic power strip for approx. 3 sec., until the “Slave on” lamp begins to blink. 5. The lamp “Slave on blinks only for a short time. During this time the standby power consumption of the master device will automatically ascertain and store the switching threshold. 6. If the lamp “Slave on” stops blinking, the setup procedure is finished. The automatic switch function can now be used.
Permanent mode with an automatic power strip with digital master-slave function.
To activate permanent mode: • Proceed as with the automatic switching threshold adjustment. • While the “slave on” light is blinking (step 5), press the button “learn” again for 3 sec. The automatic switching threshold adjustment will be finished and the permanent mode for the slave socket will be activated. To deactivate permanent mode: • Perform the automatic switching threshold adjustment again.
