Enclosure : White plastic (ABS) 100*76*41mm
(W*H*D).
Connections : Mains plug and socket to suit local electricity supply.
Sensor : Thermistor sensing element with 1.5m lead.
Voltage : 230V~
Power Handling : 600W
Control: Proportional phase angle control with soft-start (DL1) OR zero-voltage
switched burst firing (DL2)
Model DL1 Dimming (For light bulbs) proportional controller with single temperature setting.
Model DL2 Pulse (For non light-emiting heat sources) proportional controller with single temperature setting.
Model DL1ME (Magic Eye) Dimming proportional controller with day and night temperature settings.
Model DL2ME (Magic Eye) Pulse proportional controller with day and night temperature settings.
The controller controls the temperature in the vivarium to closely match the level set by the front panel adjustment and will indicate an alarm if for some reason it cannot. For the units with two settings the temperature will be controlled at the day time setting (Sun symbol) whilst light is detected by the 'Magic Eye' and at a reduced level whilst darkness is detected. The 'Night time drop' setting (Moon symbol) sets the number of degrees that the temperature is reduced during the hours of darkness. The amount of light required by the 'Magic eye' is set using the small shaft which protrudes near the cable entries.
Any alarm condition has to exist for at least 5 minutes before it will be indicated.
Indicated when the temperature in the vivarium cannot be raised to the required level even with full power applied to the heater.
Indicated when the temperature is more than 5°C below the required temperature.
Indicated when the temperature is more than 5°C above the required temperature.
If a 'High temperature alarm' is detected the heater is switched off immediately.
Lights to show that power is applied to the unit. Flicks off to indicate 'Night' (See 'Magic eye).
Flashes on and off with a 5 second period, the proportion that the light is lit within the 5 second cycle represents the amount of power being applied to the heater. E.g. If the light is lit for 2.5 seconds and off for 2.5 seconds then half power is being applied to the heater.
Note. For DL2 models power is applied to the heater whilst the 'HEAT' lamp is lit.
Flashes to indicate an alarm, the beeper sounds at the same time. The 3 different alarms are indicated by different sequences of beeps and flashes as follows :-
Heater failure One beep/flash and then a pause
(Beep Pause, Beep Pause, etc.)
Low temperature Two beeps/flashes and the a pause
(Beep Beep Pause, Beep Beep Pause etc.)
High temperature Regular beeps/flashes with no pause
(Beep, Beep, Beep, Beep, Beep, etc.)
Internal sensor detects ambient light level and the status Day/Night is indicated on the Green indicator lamp (POWER)
Day Green LED on constantly
Night Green LED Flicks off once per second.
If the unit is indicating 'Night' and should not be (Due to the light level), turn the 'Magic eye' adjustment clockwise. If the unit is not indicating 'Night' and should be, turn the adjustment anti-clockwise.
When a change from day to night or night to day is required the controlled temperature is changed slowly. It takes approximately 20 minutes for the required temperature to change from one setting to the other.
Note. As the 'Magic eye' works by detecting the ambient light level in a room ensure that it cannot see the light directly from any lamp used as a heater within the vivarium.
