Alarm channels one and two (optional)

Alarm channels one and two have SPDT relay contact outputs. The

rated current decreases for inductive loads so using suppressor

capacitors is recommended. This will also reduce the general level of

electrical noise.

alogue output (optional)

The analogue output provides you with a current or voltage based

signal that is proportional to the rate. The average output value is the

same as the rate, although the instantaneous value may differ slightly

for rapidly changing signals.

Connections

For effective protection from electromagnetic noise, all signal cables

must be shielded, or located on conductive trays or in conduits.

e 12-28 AWG Cu Wire rated for temperatures above 70 °C Only,

tighten to 4.5 lb-In. Strip wires to 7 mm from the ends. Use a suitable

ferrule for multistranded wires (do not solder).
