– All power supply and signal cables are installed and connected.
‡ The following tools and equipment are required:
â– Personnel protection, for example, against hot or corrosive measurement gases
â– The following tools are essential:
– 2 x 24 mm open-ended spanners or box wrenches for mounting the measuring
probe on the duct
– 1 x 19 mm open-ended spanner or box wrench for mounting the measuring probe
on the SR unit and for optical alignment
– Hexagon socket screw key set
– Insulated screwdriver set for electrical work, and so on.
â– Fastening parts supplied with the GM35 measuring system:
– 4 bolts M16 x 60 with washers and self-locking nuts for securing the probe to the
flange on the duct side
– 3 nuts with washers and 10 disk springs in each case for securing the measuring
probe to the SR unit (see Page page 49)
– Seal for sealing the measuring probe and SR unit connection
â– Optics cloths without detergents, for example, SICK-MAIHAK order no. 4 003 353
â– If a weatherproof cover is used, an adhesive is required to attach the fixing bolts on
the SR unit. A quick-drying epoxy resin adhesive is recommended.
â– Depending on where the SR unit is adjusted (see Chapter 6.4), the following accesso-
ries may be required:
– Adjustment at the measuring point: angle flange (order no. 2 017 833) or suitable
test bracket (supplied by the customer) for securing the SR unit and measuring
probe.
Adjustment elsewhere: an additional power supply cable with connector for the SR
unit, and (if a GPP measuring probe is used) for the measuring probe (order no.
2 017 519, see also „Adjustment elsewhere“ on page 51 and Chapter 6.4.2 on
page 52). In this case, the angle flange is not used. A test bracket (provided by the
customer) or suitable support is used instead.
