3.4.7. CONNECTING THE ALARM RELAY OPTION (OPT 61)
The T200H/M can be equipped with a set of 2 concentration alarms. Each alarm can be
independently enabled or disabled as well as programmed with its own, individual alarm
limit point (see Section 4.14 for details on programming the alarms).
The status of each alar
m is available via a set of alarm relay outputs located on the lower
right hand corner of the analyzer’s rear panel (see Figure 3-4). While there are four
relay
outputs on the back of the analyzer, only Two of the outputs correspond to the
instrument’s two concentration alarms.
