W A R N I N G
Potential Electrocution Hazard. Power and relay terminals are
designed for only single wire termination. Do not use more than one
wire in each terminal.
W A R N I N G
Potential fire hazard. Do not daisy-chain the common relay
connections or jumper wire from the mains power connection inside
the instrument.
C A U T I O N
Fire hazard. Relay loads must be resistive. Always limit current to the
relays with an external fuse or breaker. Obey the relay ratings in the
Specifications section.
The analyzer has two alarm relays. The relay outputs are not powered.
Each alarm relay is associated with one alarm (e.g., Alarm A or Alarm B)
and energizes when that alarm occurs. The alarm relays are enabled or
disabled in the alarm settings. Refer to the operations manual to
configure the alarm settings.
Note: More alarm relays (maximum of twelve) can be added. A maximum of six 2-
channel signal output modules or one 8-channel signal output module can be
connected to the analyzer.
Refer to Table 5 and Figure 13 on page 14 to connect the alarm relays
to a control or alarm device.
