1 Safety The following symbol marked on the equipment means:Caution: Read these operating instructions fully before use and pay particular attention to sections containing this symbol Always observe the following safety precautions • • • • • • • • • • Use only as specified by the operating instructions, or the intrinsic protection may be impaired. After transport or storage in humid conditions, dry out the unit before connecting it to the supply voltage.
3 Controls and indicator lamps Case rear view (Figure 1) Yellow L.E.D indicator (12V) IEC Mains Socket 12V Dc Cable 12V Cigar lighter plug Control Panel (Figure 2) Grant Set Temperature Controller temperature display (see fig 3) Fuses 1AF 5AF Fuses Block Run/Charge Power Switch Run Charge Red L.E.D Power Indicator (240V) The run/charge switch when in the run position is used to start unit and in the charge position charges the internal battery.
4.0 Operation 4.1 Mains operation 240V Plug the mains lead into IEC socket at rear of case and connect to a mains 240V power supply. Set the switch on the control panel to the “Run” position and check that the red L.E.D is illuminated onthe control panel. The temperature display will display the block temperature. 4.2 Internal battery operation As mains operation, but with mains power lead disconnected. If the display does not light the internal battery is not charged.
4.8 Start up At start up the instrument performs a lamp test for a few seconds where the display and the leds blink, in order to verify the integrity and correct operation. LED Position out ºC 4.9 Associated function Relay 1 Setpoint Status ON for heater activation ON When setting the set point Overtemperature To protect both the unit and your samples, the unit has a cycling thermal switch located inside the unit and operates at 50°C.
