Introduction
The TP-4 is a 3 1/8" (80mm) sunlight readable 4 channel universal analog input color display instrument. Each channel
can be individually programmed to display either pressure, temperature, current or volts from a universal analog input that
can interface to many sensors such as oil temperature, coolant temperature, oil pressure, fuel pressure, manifold
pressure, boost pressure and many more.
The TP-4 can display any combination of 1 to 4 analog channels in a horizontal / vertical bargraph or a numeric display
format.
Pressure can be measured using standard automotive resistive senders (e.g. VDO 2, 5 and 10 Bar), Rotax 4-20mA
senders as well as voltage output pressure senders (e.g. UMA). Temperature can be measured using standard
automotive resistive senders (e.g. VDO, Westach) as well as the MGL Avionics precision LM335 semiconductor sensor.
In addition the temperature, pressure and current inputs can be programmed to a user defined curve for custom senders.
All analog channels have a programmable low and high alarm. This results in a contact closure that is typically used to
switch a warning lamp on. The TP-4 also records the minimum and maximum values reached for each channel in
permanent memory.
The TP-4 can also be interfaced via the CAN bus to an external RDAC unit (Remote Data Acquisition Computer). This
allows for easier installation as the RDAC unit is normally mounted in the engine compartment.

The internal pull up resistor dip switch for the resistive temperature sender input must be in the “ON” position. - Page 22 Blaze TP-4 Operating Manual Page 22 10.3 Senders that are grounded in the engine block Single wire senders require that their mounting arrangement (thread) has a very good electrical contact with the engine block. Avoid the use of any sealant or tapes as these may cause a bad electrical connection. Further to this it is very important that the engine block has a good electrical connection to the negative supply terminal of the TP-4.
- Page 23 Page 23 10.6 Closed Loop Current Sensor The MGL Avionics magnetic closed loop current sensor provides a 0.5V to 4.5Vdc output voltage which is proportional to a 50A bi-directional input current. Advantages of closed loop current sensors over conventional current measurements techniques is that they provide the highest accuracy, are ideal for noisy electrical environments and they provide complete electrical isolation f rom the current carrying conductor.
