Connect the unit as required. If the Delayed Pulse function is required, place a link between terminals A1 and B1. Installation work must be carried Setting the unit. • Set the “tOFF” and “tON” “Range” selectors to the required position (depending on whether seconds, minutes or hours are required). • Set the “Set %” adjustment for the “tOFF” and “tON” as required. The “Set %” is a % of the selected range, so 60% of the 1 – 10 hour range will give 6 hours.

CE, C-tick and RoHS Compliant. EMC: Immunity: EN 61000-6-2 (EN 61000-4-3 10V/m 80MHz - 2.7GHz) Emissions: EN 61000-6-4 Applying power. • Apply power and the green LED will start flashing to indicate timing is in progress. • The red relay LED will illuminate to indicate the relay is the energised state when the “tON” delay is running. • When the “tOFF” delay is running and relay is de-energised, the red LED will remain extinguished. • If the Delayed Pulse function is selected, the green LED will stop flashing and remain illuminated when the relay de-energises after the “tON” period. Note: 1 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 (reset) duration and levels are defined in the product standard however, the standard allows for these to be different from the levels actually specified. 2 Link terminals A1 and B1 for Delayed Pulse SETTING DETAILS 1.
