• INSTALLATION AND SETTING Installation work must be carried Dielectric voltage: Rated impulse withstand voltage: 4kV (1.2/502kV AC (rms) IEC 60947-1 µS) IEC 60664
• BEFORE INSTALLATION, ISOLATE THE SUPPLY. out by qualified personnel. Housing: Orange flame retardant UL94
• Connect the unit as required. Weight: ≈ 80g
• If the Delayed Pulse function is required, place a link between terminals A1 and B1. Mounting option: On to 35mm symmetric DIN rail to BS EN 60715
or direct surface mounting via 2 x M3.5 or 4BA screws
Setting the unit. using the black clips provided on the rear of the unit.
• Set the “tOFF” ➍ and “tON” ➏ “Range” selectors to the required position (depending on whether Terminal conductor size ≤ 2 x 2.5mm [2] solid or stranded
seconds, minutes or hours are required). Approvals: Conforms to IEC 61812.
• Set the “Set %” adjustment for the “tOFF” ➌ and “tON” ➎ as required. The “Set %” is a % of the
selected range, so 60% of the 1 – 10 hour range will give 6 hours. Gy)ustes IND. CONT.E111187 EQ.
Applying power. CE, C-tick Cc and RoHS Compliant.
• Apply power and the green LED ➊➊ will start flashing to indicate timing is in progress. EMC: Immunity: EN 61000-6-2 (EN 61000-4-3 10V/m
• The red relay LED ➋ will illuminate to indicate the relay is the energised state when the “tON” ➋ will illuminate to indicate the relay is the energised state when the “tON” will illuminate to indicate the relay is the energised state when the “tON” ON” ” 80MHz - 2.7GHz)

- Apply power and the green LED ➊➊ will start flashing to indicate timing is in progress. - • The red relay LED ➋ will illuminate to indicate the relay is the energised state when the “tON” ➋ will illuminate to indicate the relay is the energised state when the “tON” will illuminate to indicate the relay is the energised state when the “tON” ON” ” 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._ - _2 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._ **==> picture [98 x 7] intentionally omitted <==** **----- Start of picture text -----**
