In this way, when both the Safety function A and B of the Safety Module are not in the Safe(HWBB) state, Un015
shows a input signal condition of the CN8.
When when either the Safety function A or B of the Safety Module are in the Safe(HWBB) state, Un015 shows only
OFF (high level) regardless of the input signal condition of the CN8
Therefore, when using this monitor, the Safety function of the Safety Module should not be activated.
