of Channel 1 (MA1 and MAt1), and Maximum Value of Channel 2 (MA2 and
MAt2). See the diagram below. Please note that time is expressed in seconds
when it is less than 9999 seconds. Time longer than 9999 seconds will be
displayed as Hours. Minutes (hh.mm).

5. DOWN key “V”. In the Parameter Setting Mode, press it to scroll the
parameter list in a reversed order or decrease the parameter value. In the Peak
Value Checking Mode, press it for 2 seconds to reset the peak values stored in
the memory. In the Normal Operating Mode, press this key to toggle the
display the current readout and value difference if the feature is enabled.

6. UP key “Λ”. In the Parameter Setting Mode, press it to scroll the parameter
list or to increase the parameter value. In the Normal Operating Mode, press
this key to toggle the display brightness between bright and dim. Each time the
key is pressed the display brightness will be changed.

C.2 General Wiring Rules

1. T6 and T7 are 12 VDC power input for the controller.

2. T1-T5, T13, and T14 are for different types of input signals. T1 is the circuit
ground for all input signals.

3. Wiring of Thermocouples (TC). For Channel 1, connect the positive side of
the TC to T2, the negative side to T1. For Channel 2, connect the positive side
of the TC to T3, the negative side to T1. (See Figure 4(a).)

4. Wiring of Resistance Temperature Detectors (RTD). In Channel 1, for a
three wire RTD, connect the two red wires to T1 and T2, connect white wire to
T4; for a two wire RTD, connect the red wire to T2, and connect the white wire
to T4, and short T1 and T2. In Channel 2, for a three wire RTD, connect the
two red wires to T1 and T3, connect white wire to T5; for a two wire RTD,
connect the red wire to T3, and connect the white wire to T5, and short T3 and
T1. (See Figure 4(b).)

5. Wiring of Pressure Sensors. In Channel 1, connect the power source wire of
the sensor to T9, the signal wire of the sensor to T13, and the ground wire of
the sensor to T1. In Channel 2, connect the power source wire of the sensor to
T9, the signal wire of the sensor to T14, and the ground wire of the sensor to
T1. (See Figure 4(c).)

6. Wiring of mV and mA signals. Wiring for these signals are similar to
thermocouple sensors.

7. T8 is for display brightness control. When connecting the illumination signal
(+12 VDC) to it, the brightness with synchronized with headlight. If not
connected, the brightness can still be controlled by UP key “Λ”. Use T8 and T7.

8. Wiring for relay output. J1 and J2 are two normally open relays. T10 is a
common pole for both relays. Use T12 and T10 for J1 relay. Use T11 and T10
for J2 relay. (See Figure 4(d).)

D.1 Basic Parameters (Press SET key then enter 0089 to enter setting mode)
D.1.a) Basic Parameters

The gauge SYL-2813 has two input channels that can read signals from two
different sensors simultaneously. Each channel can have its own input sensor
type, specified scale range, and input offset. See Table 3 for a list of basic
parameters, description, range, and initial values. A list of valid types of input
sensor is given in Table 4. Please note that all 19 input types are available for
Channel 1, but the last three input types in Table 3, i.e., 0 - 10 mA, 0 - 20 mA,
and 4 - 20 mA, are not available for Channel 2.
