Safety Information WARNING: Toxic and caustic substances in parts in contact with sample gas ● GM700 parts in contact with sample gas can contain toxic and caustic sub- stances depending on the sample gas composition. ● When fitted in the measuring device, the reference cuvette contains the respective gases to be measured.
Laser capacity The laser wavelength varies for the respective measuring components. The laser output capacity is <10 mW on the optical interface (front window) of the GM700 SR-unit. The emitted radiation is harmless to human skin. Behavior during purge air failure 1.2.3...
Product Overview Evaluation unit The evaluation unit in the GM700 measuring system serves as user interface and is responsible for measured value processing and output as well as control and monitoring functions. The EvU can be located in the vicinity of the SR-unit. It can also be located up to about 1000 meters from the sampling point, e.g.
(TDLS) or Tunable Diode Laser Absorption Spectroscopy (TDLAS). A laser specially developed for gas analysis is used as light source in the GM700. This laser diode radiates a wavelength with a narrow line width so that an absorption line can be reli- ably scanned.
● Start-up The actual start-up is carried out by trained personnel or Customer Service. This work is described on §6 ( p. 47). The main activities are adjustment tasks on the GM700 sys- tem related to the application. Project Planning Checklist 3.
Mounting the flanges with tube 3.3.3 SICK delivers two flanges with tube with 240 mm total length and 125 mm inner diameter as standard. A version with 500 mm total length is available for installation locations with thicker insulation or for stone stacks. Special versions can be manufactured on request.
The onsite supply and signal cables are laid beforehand to facilitate subsequent installa- tion and start-up of the GM700 system components. Suitable cable ducts resp. empty con- duits are installed for cables already prefabricated and delivered with the GM700 system.
Installation Preparations 4. 1 This Section describes the assembly and installation work for the GM700 measuring sys- tem before the actual start-up. Completion of the onsite preinstallation according to p. 19, §3 is assumed. Checking the scope of delivery 4.1.1 ▸...
User qualifications 5. 1 This Section describes how to operate the GM700 measuring system with the evaluation unit (EvU). The evaluation unit is available with either a sheet metal enclosure (protection class IP 65) or a cast-metal enclosure (protection class IP 67). The work described in this Section can be carried out by qualified customer operating personnel.
● Exact adherence to the application requirements specified in the order ● The possibility, during start-up, to ask the advice of a trained specialist from SICK or the respective sales partner should special questions arise that go beyond the normal scope of the standard procedures described.
Make sure the supply voltages on the type plates of the GM700 device components comply with the installation conditions. The supply voltage of the GM700 components can be changed between 115 V and 230 V on site by the SICK service personnel when necessary.
Start-up This Section describes the final preparations at the measuring point at which The Ausfüh- rung mit Messlanze GM700 starts measuring operation. The SR-unit and reflector with fit- ted purge air fixture must already be installed at the sampling point.
Make sure the nitrogen cylinder does not run empty. Close off the nitrogen cylinder for safety reasons when the measuring system has been shut down. The device first performs an initializing cycle after the power supply for all GM700 compo- nents (evaluation unit, purge unit) has been switched on. The evaluation unit displays the message “Initialization”.
The maintenance intervals depend on individual application conditions and should be clar- ified with SICK Service resp. a trained engineer or technician at the local sales partner. If no other specifications have been made, the following recommendation is applicable: ●...
▸ Always switch the GM700 SR-unit off or disconnect the SR-unit CAN cable to the evaluation unit during work on the SR-unit or on the reflector. Otherwise, this could result in dangerous exposure to radiation.
Filter box measurement to check the measuring channels for NH , HF or HCl 7.5.3 The gas filter box serves to check the GM700 with test gases. Requirements Components required: ● Reflector enclosure with gold-plated hollow triple reflector; Part No. 2030206 ●...

This is the standard case for GM700-2 (HF). A test gas system with hose pump, scales and evaporator is required in addition to the heated test cell GMK10 (example: Hovacal).
Select “Maintenance Mode” and activate maintenance operation Assembly of the GM700 components with the test cell GMK10 7.6.1 Fig. 50 Assembly of the GM700 components and the test cell to a zero path GM700 reflector unit Zero path GMK10 test cell GM700 SR-unit ...
1 Step: Checking optical alignment Checking optical alignment p. 56, 6.4.4 CAUTION: It is possible to perform the check of the GM700 with a separate reflector on a zero tube or a similar construction. Independent therefrom, the optical alignment is always performed to the probe position (marking “O, circle”...

Terminate the measurement with the “ back” button. Reinstall the GM700 SR and reflector unit to the purge air fixtures at the sampling point and continue Measuring mode. NOTICE: Purge the mesuring system with evaporated distilled water ...
Damage to the measuring system itself Depending on the installation conditions and measuring system version, a purge air failure could cause damage to the GM700. Section p. 86, 8.2 describes the necessary emer- gency and protective measures. Purge air failure 8.
2.5 AT, 250 V Evaluation unit not responding ▸ Check the power supply on the GM700, check the operating voltage set ▸ Check the fuse in the evaluation unit; check the 24 V/5 V supply indicator in the evalu- ation unit, when doing so, remove the plug-in terminal on the cable to the receiver.
