different units. For example, if Channel 1 is reading an EGT probe showing
1000°F, while the Channel 2 is reading a pressure sender showing 50 PSI,
when you press the DOWN key, the lower window will show 950.
E. Application Examples
E.1 Measuring Exhaust Gas Temperature (EGT) and Boost Pressure.
The SYL-2813 gauge has two input channels and it can read two different
types of signal simultaneously. The wiring diagram of connecting an EGT
sensor and a MAP sensor to SYL-2813 is shown in Figure 8. The steps for
setting up the gauge for this application is also given in this section.
E.1.a) Wire the EGT sensor (K type thermocouple in this example) and the
MAP sensor (AUBER-303) as shown the Figure 7, where the EGT sensor is
connected to channel 1 and MAP sensor is connected to channel 2.
E.1.b) Press SET, change the code to 0089 to enter the Basic Parameter
Setting mode. Set
Int1
to “k” and
Int2
to “0-5v”.
E.1.c) To display the pressure in Bar with 0.01 bar resolution, set the decimal
point
dot2
= 2 (this step needs to be done before set
PuL2
and
PuH2
). Set the
PuL2
= -0.38 and
PuH2
= 03.38. (Please see the installation guide for AUBER-
303 from the product page on our website).
E.1.d) To display the pressure in PSI with 0.1 PSI resolution, set the decimal
point
dot2
= 1. Set
PuL2
= -05.4 and
PuH2
= 048.9.

E.2 Measuring Exhaust Gas Temperature (EGT) and Oil Temperature.
To measure temperatures with one thermocouple sensor and one RTD sensor,
you can wire the sensors to SYL-2813 gauge as the diagram in Figure 9. In this
diagram, the thermocouple is connected to the Channel 1, and the RTD sensor
is connected to the Channel 2. You will need to change the input types and
other parameters for Channel 1 and 2 accordingly.
E.3 Read Temperature Difference Between Two Probes.
In this example, a type K thermocouple is wired to channel 1, and a PT100
probe is wired to channel 2 (see Figure 10 for wiring). To set up the gauge to
show the temperature difference in the lower window, please use access code
0036, and then set parameter
Fun1
= on. In normal operation mode, the top
display will show reading from probe #1, and the lower display will show
reading from probe #2. To check the difference, press the DOWN “V” key
shortly, and the lower display will show the difference. Press the DOWN key
again, lower display will be switched back to reading from probe #2.
