Cross Triggering
Any number of TR-2100 recorders may be coupled together to form a system with any
number of inputs (in multiples of 8, 16, 24, or 32 analogue inputs). This system uses the
'Triggered' status relay outputs and digital input 15 of each recorder. They are connected as
follows:

Figure 7 Cross-Triggering Wiring
Switch 5 in bank SW1 on the acquisition board must be ON for every machine connected
together in this way. When this is done and the systems are switched on the channel labels
for digital input 15 will become 'Cross-trigger'. The triggering for these channels must be
enabled manually but are automatically set as level sensitive with profiling off.
Operation
When any of the connected recorders is triggered, its 'Triggered' status output relay will
pulse immediately. This will cause digital input 15 on each recorder to go into the alarm
state. When this happens, the recorders will trigger, but their status relays will not be
activated. If a valid trigger is detected on a recorder other than that which started the
process, its status relay will activate, thus extending the post fault period of all recorders if
necessary.
