Introduction
Safety Manager has 3 different key switches: • Figure 8 shows the front view of the Battery and Key switch module (BKM), where the Reset and Force Enable key switch are installed. The key switches on the BKM are wired to both CP1 and CP2. – Under normal circumstances the Reset key switch is used to start the system or restart halted system components without switch-over effect. (Turning this key switch will not interrupt process safeguarding.) – When performing on-line modification (changing the application / system configuration on-line) the Reset key switch is used to switch applications. – The Force key switch is used to enable / disable the use of forcing of IO points. With this key switch in the “on” position, forcing via a safety station is allowed. With this key switch in the “off” position all forces are cleared • Each Quadruple Processor Pack (QPP) has a 3 position key switch is installed. – The key switch on the QPP is used to idle, halt or run the QPP. When idle, the QPP can be fitted with a new application program.
