15.3.3 THE STATUS MODULE

On the status module, by the group alarm message of the TCU a changeover relay and a solid-state

relay are connected. These can be used for alarm indication. In addition, external sample gas pumps

can be switched off via two further solid-state relays e.g. in the event of an alarm and switched on

under good conditions. For external control of the pumps, see Section 12.4.2.
