In Case of Digital Input of Main Controller A (Ex.) Monitor Display
1. Convert the upper and lower number in the hexadecimal number 2 digits display section.
(Refer to Correspondence Chart between Hexa-decimal Number and Binary Number).
Upper 6 0110
Lower 0 0000
Therefore, binary number 01100000 can be ob-tained.
2. This value corresponds the bit on the Binary Number Bit List (refer to T5-1-11), as follows:
bit 7 ⇔ 0 Main Controller Selection Switch = 0
3. If the value is "1", the terminal point correspond-ing the bit is closed. The contact terminal is con-nected to ground, so that power flows.
If the value is "0", the terminal point is opened, so that current does not flow. (Refer to Diagram 1) From the above information, it becomes apparent that the engine oil level indicator on the monitor is switched on, the heavy lift switch is turned on, and the checker is disconnected.

In Case of Digital Output of Main Controller A (Ex.) Monitor Display
1. Convert the upper and lower number on the hexadecimal number 2 digits display section.
(Refer to Correspondence Chart between Hexa-decimal Number and Binary Number).
Upper 5 0101
lower 1 0001
Therefore, binary number 01010001 can be ob-tained.
2. This value corresponds the bit on the Binary Number Bit List (refer to T5-1-11), as follows:
bit 7 ⇔ 0 Engine Exhaust Gas Temperature Alarm Output
bit 6 ⇔ 1 Engine Oil Pressure Alarm Output
3. If the value is "1", the controller internal voltage at the terminal corresponding the bit is connected to ground, so that power flows.
If the value is "0", the controller internal voltage at the terminal corresponding the bit does not con-nected to ground, so that power does not flow.
(Refer to Diagram 2)
From the above information, it becomes apparent that the engine oil pressure indicator is turned on, and motion alarm and auto-idle control are acti-vated.
4. Convert the value for digital output 1 of the main controller B. Then, calculate the corresponding bit values.

1. Convert the upper and lower number on the hexadecimal number 2 digits display section.
(Refer to Correspondence Chart between Hexa-decimal Number and Binary Number).
Upper 6 0110
lower 0 0000
Therefore, binary number 01100000 can be ob-tained.
2. This value corresponds the bit on the Binary Number Bit List (refer to T5-1-11), as follows:
bit 7 ⇔ 0 Heavy Lift Solenoid Valve Output bit 6 ⇔ 1 #1,#2 Pump Power Decrease Solenoid
Valve Output
bit 5 ⇔ 1 #3 Pump Power Decrease Solenoid Valve Output
bit 4 ⇔ 0 Blank = 0 bit 3 ⇔ 0 Blank = 0 bit 2 ⇔ 0 Blank = 0 bit 1 ⇔ 0 Blank = 0 bit 0 ⇔ 0 Blank = 0
3. If the value is "1", power flows at the terminal corresponding the bit.
If the value is "0", current does not flow at the terminal. (Refer to Diagram 3)
From the above information, it becomes apparent that power flows on the #1, #2 power decrease solenoid valve and #3 pump power decrease so-lenoid valve.
