2. Range of use
The TLS 100 E anti-dry-running feature is an electronic flowswitch with an adjustable cut-out timer used as a
protective feature to prevent electrical pumps, domestic booster sets and similar devices from running dry in the
absence of water.
Upon power-up, the TLS 100 E will activate the electrical pump and keep it running as long as a specific quantity
of flowing liquid is present inside the line. As soon as the water flow inside the line ceases, the electronic
monitoring device will activate a timer which will cause the pump to cut out after the lapse of a specific, adjustable
period of time.
The activation of the time is indicated by the flashing of the red indicator lamp. As soon as the set time span has
elapsed, the device will check whether the downstream pump is still consuming a specified amount of electrical
power. If the required current strength is less than 1 Ampère, the device will switch to “standby” mode, and the
pump is ready to return to operation at any time. If after the lapse of the specified time window the demanded
current strength is above one Ampère, the TLS 100 E will interrupt the flow of current to the pump and switch to
the “error” condition. This condition is indicated by the uninterrupted lighting of the red indicator lamp.
Resuming the pump's operation is impossible without pressing the reset key on the TLS 100 E. Before that,
please be sure to remove the cause of the dry-running of the connected pump.
This product is intended for private use in the home area and not for commercial or industrial purposes.
The TLS 100 E anti-dry-running feature is not suitable for pumps with a power consumption of
less than 230W.
