DAVIES CRAIG LCD CONTROLLER FOR EWP & DIGITAL FAN
Building on the success of the 8000 model of digital EWP and fan controller, the new 8001 controller adds more features and safeguards to make sure that your engine is performing within its optimum temperature range.
The new unit features a black and white high contrast LCD screen which displays real-time data regarding the engine targeted and set temperatures. A flashing EWP logo in the top left of the screen signifies the pump pulse, width, modulation (PWM) operation, delivering the desired coolant flow through the engine.
Take control of the cooling parameters of your engine with targeted and set temperatures which can be adjusted from 60°C (140°F) to 100°C (212°F). These temperatures are now stored in the unit memory for recall for when the battery is disconnected.
Other display features include an override feature to assist with electric water pump bleeding operation and also a voltage output.
Also included in the digital controller is a suite of self-diagnostic test functions which provide visual and audible warnings which enable simple trouble-shooting and extra protection against engine damage. These warnings are highlighted as below:
- If the coolant temperature doesn't exceed 40°C (104°F) within the first 5 minutes after start-up.
- If the coolant exceeds 10°C (+50°F) of set/targeted temperature.
- If the coolant temperature exceeds 100°C (212°F)
- If the voltage supply is either too high or too low.
- If there is an error with the electric water pump.
- If there is a temperature sensor error.
As per the previous model of EWP and fan controller, the 8001 manages the operation of your water pump automatically by varying the pumps speed in relation to the engine coolant temperature as well as regulating the fan speed to assist in thermal control.
The digital fan controller also doesn't just stop protecting as soon as the engine is shut down, it will still operate the EWP for up to 3 minutes after the ignition is cut to circulate coolant to rapidly dissipate more heat to avoid heat soak.
Setting the coolant parameters is via a simple push button system, with the unit set by default to 85°C (185°F)
