Theory 

The 'TEST' terminal acts as an input when the unit is about to pulse, and will 
cause the instrument to enter a paused state (not pulse) if you apply a 
connection to ground. Each unit also drives its own 'TEST' terminal to ground 
when it is busy pulsing. These two functions combined mean that if two or more 
units have their 'TEST' terminals connected in parallel, and share a common 
ground, then at any tim

e when one is pulsing, it will ground the ‘TEST’ terminals 

of all units it is connected to, and temporarily pause them until it is finished, then 
release them. The next unit, which is ready to pulse, then does the same thing in 
turn, and the process repeats.

 

 

 

 

The connections above also include the normally open contact of a relay 
programmed into Failsafe mode in line with the ‘TEST’ terminals. The function of 
this is simply to prevent a possible lock up of the whole system if one unit has a 
problem (such as power failure). Any time that a unit is in the failed state, it will 
be disconnected by the relay from the other units, so they can continue working 
together.
