l This sensor uses ONE Controller Interface I.S. Module position
l Start with the Connections table and “Typical Installation" drawing below.
l Measure the length of the circular space in the monitoring pipe from top to bottom and subtract 1.3 cm
(0.5 in.) for a total measurement to be used for the sensor installation.
l Measure the calculated length from the sensor tip along the sensor cable and identify it with tape or a
marker.
l Put the sensor and wire through the monitoring opening until the mark is level with the top of the
opening.
IMPORTANT: To prevent false alarms, the sensor must not touch the bottom of the
monitoring tube
l Connect the sensor wires to the field wires in the junction box. Use the supplied cable gland and silicon
wire nuts.
l Seal the electrical connections with the epoxy seal packs (refer to M00-390008 Waterproof Electrical
Connections for instructions).
l Install explosion-resistant sealing fittings at both ends of the conduit. Refer to the Probe-Cable Seal-
offs section of the console's Installation Guide for instructions.
