connected to STOP and NO is connected to START.
3. The logic components of transistor, FET and couplers can be connected and used as
control circuit. The connected signals and circuit are shown as Figure 4-3 below. To use
this circuit to control the system, it must contain the following:
(1) The current of LOW signal is 2mA or less.
(2) The active time for input signal is more than 20mS.
4. Either the relay switch control in Figure 4-1 or the coupler control in Figure 4-3 uses the
contact of components for control action. It can prevent the error operation from
interference effectively. Though the system has a lot of precautions, it is necessary to be
careful the interference caused by the measurement system settings.
5. The pin assignment of REMOTE CONTROL is shown as below figure. It should be
memorized when using external control.
