5. Zu Kap. 6.7 „Montage der elektrischen Verbindungsleitung zwischen
Leckagesonde und Meldeeinheit VL-H9/ME-MV-LS“
(1) (1) has been added to:
legal external capacity 640 nF
legal external Inductivity 3 mH
6.7.1 „Installation of the leakage probe“ has been added to this section
(1) These comments, with regard to the risk-analysis are for a leakage probe without coating,
type FTL 10 maufactured by Endress und Hauser, and a controlling device Typ FTL 325 N.
(2) In general the leakage probe is installed in the installation kit.
(3) The leakage probe has be installed in accordance to the valid Standards and regulations
(e.g. IEC 79-14).
(4) The temperature at the probe (liquid temperature) shall not exceed 85°C.
(5) The ambient temperature of the liquid probe shell not exceed 60°C.
(6) Use a suitable line entrance for connection the probe (see EN 60079 Kap. 10.3)
(7) To observe the system of protection IP 66/67, the cover of the probe’s housing and the line
connection has to be installed profesionally. Not used entrances shall be closed with
suitable (Ex-d)-approved plug.
6. To section 8.1 “General Notes”
(3) to (5) has been added to this section:
(3) To clean the leak detector VL-H9/Ex or the working unit VL-H9/A-..-Ex, use a moist cloth.
(4) For exchange or repair-work take care that the venting-measures are given (Distance
between housing and flange plate >2.5 mm)
(5) Connect only suitable equipment to the 3-way cocks in suction and measuring line
(categorie 1 for interstitial spaces of zone 0, categorie 2 for interstitial space of zone 1)
7. To section 8.2 “Maintenance”
(5) to (7) have been added to this section:
(5) The conditions in section 6.5.1 must be observed and complied with at all times.
(6) As part of the annual function test, check the motor of the pump for running noises
(damaged bearings).
(7) If the pump has to be changed or when working on the pumps exhaust line a pressure of
the suction- and measuring with 10 bar has to carried out for the parts inside the housing.
(8) Additionally for the VL-H9 using a solenoid valve
– If the solenoid valve must be exchanged, take care that the leak detections system is
unpressurerized and free of liquid.
– Pull never the solenoid from the body while the voltage is on.
