4.4.4. Hi-Current Relay Outputs

Three form C relay outputs are provided on the rear panel on the nine pin connector
(See Figure 4-6). The relays are labeled "Relay 1," "Relay 2," and "Relay 3."
The relays are dry contact type form C (SPDT) relays with Normally Open (N.O.),
Normally Closed (N.C.) and Common (COM) contacts. The relays are capable of
driving loads of up to 250VAC, 5A. For maximum contact life, the relays should
only be used to drive resistive loads. Contact life may be dramatically shortened if
inductive loads are driven without any provision for minimizing high voltage
"inductive kick" that can occur.
These relays have slightly different functions depending on whether the monitor is a
single stream or multi-stream configuration.

* The state of the global alarm represents all the Hi or Hi-
Hi alarm states OR'd together, i.e. if the Hi alarm for one
or more of the sample streams is activated, then the
Global Hi alarm will be activated.
