■ INPUT MONITOR: The input 0 – 100% is converted into a combination of 1-second (1 unit) and 0.25-second (0.2 unit) cycled
pulses. 1 unit corresponds to 25%, while 0.2 unit corresponds to 5%. 0% equals to 1 unit, while 100% cor-
responds to 5 units. The input % is represented in the total number of 1-unit pulses and 0.2-unit pulses,
repeated in the sequence of '1-unit pulses ––> 0.2-unit pulses ––> OFF for 1 second or more.'
[Examples]
0% = 1 unit
25% = 2 units
30% = 2.2 units
45% = 2.8 units
50% = 3 units
100% = 5 units
■ ERROR MONITOR: Indicates the transmitter's error status.
Lower overrange: The input signal is lower than the out-
put's lower range limit.
