Wind indicator relay JSL-1E mechanical
Technical data
Application
Housing colour:
grey (lower part like RAL 7016, upper part like RAL 7035)
Monitoring of air flows in ducts, in air supply and air exhausting devices of fans or electrical heat registers. The wind indicator relay is set to the minimum switching points at the factory. The switch-on/ switch-off values can be increased by turning the inner screw clockwise. Fitting is done in the vertical paddle position from the top in a horizontal pipe/duct.

Mounting: The device can be mounted in any alignment, but attention must be paid to the correct direction of flow. When fitting in a vertical duct, the weight of the vane must be balanced at the range screw, which results in changed switching values. Attention: Owing to the changed switching values, at flows near the minimum set value the wind indication relay may not function properly! At air speeds higher than 5 m/s, owing to the danger of breakage, the vane must be cut on the sides where indicated. This increases the minimum switch-off value set at the factory from 1 m/s to 2.5 m/s. A calming path that is 5 times the duct diameter must be provided before and after the assembly location. The scope of delivery includes a seal to be fitted between the duct and the device. Function: The devices are set to the minimum switch-off value at the factory. A higher value can be selected by turning the range screw to the right. If the flow exceeds the value that has been set, contacts 1–2 close and the corresponding assembly is enabled. If the flow drops below the value that has been set, contacts 1–2 open and contacts 1–4 close.
