LMMT-6-A 2506 HS Code: 85364900 Country of Origin: UK Dims: to DIN 43880 W. 17.5mm INSTALLATION AND SETTING

• BEFORE INSTALLATION, ISOLATE THE SUPPLY.
• Connect the unit as required. Setting the unit.
• Set the “Function” selector ➎ to the required position 1.
• Set the “Range” ➍ to the required position (depending on whether seconds, minutes or hours are required), then set the “Set %” adjustment ➌ as required. The “Set %” is a % of the selected range, so 60% of the 1 – 10 hour range will give 6 hours. Applying power.
• Apply power and the green LED ➊ will illuminate or start flashing depending on Function selected. If a Switch initiated function is selected, the LED will begin flashing upon closing of the external input.
• The red relay LED ➋ will illuminate to indicate the relay is in the energised state. Note: 1 If the “Function” selector is changed whilst the power is applied, the relay will remain in its current state and the green LED will flash at a faster rate. Power must be removed and re-applied for the new Function to operate. 2 In accordance with IEC 61812, the green LED is permitted to extinguish during a voltage dip or momentary interruption of the power supply providing the state of the output relay does not change. The dip / interruption duration and levels are defined in the product standard.
