1.2 Operation
To operate the H 7033, set the following parameters:
•In ELOP II Factory/SILworX, set transmitter supply of the module MI 24 01
MI[xx].Transmitter Used to "FALSE".
•Set the power supply (L+) H 7033 to the following value:
L+ = UTmin + ITx Rwire + 4 V, UTmin = minimum transmitter supply voltage
•Use the IMIH terminal if the filtered input signal of the three-wire transmitter should
be used.
1.2.1 Monitoring of the Transmitter Supply Voltage UTM
To monitor the transmitter supply voltage UTM, connect the analog input of the MI 24 01
module to the SM and L- terminals. The transmitter supply voltage UTM is monitored via the
current IMI24, see the following formulas:
IMI24 = UTM / 3200 Ω
UTM = UTmin + ITx Rwire+ UFuse 500 mA + Tolerance
Example:
UTmin = 24V, IT= 200 mA, Rwire= 5 Ω, UFuse 500 mA = 0.4 V, Tolerance = 0.9 V
IMI24 = (24 V + 1 V + 0.4 V + 0.9 V) / 3200 Ω
IMI24 = 8.22 mA
The input current of MI 24 01 must not fall below 8.22 mA.
The module MI 24 01 checks the transmitter supply voltage UTM. If UTM is less than the
minimum transmitter operating voltage UTmin, the signals from the connected transmitter may
no longer be classified as safe.

1.4 Mounting the H7033 in Zone 2
(EC Directive 94/9/EC, ATEX)
If the special conditions X are observed, the H 7033 device may be installed in Zone 2.
The corresponding EC declaration of conformity is available on the HIMA website.
Special Conditions X
Mount the device in an enclousure (cabinet) that meets the EN / IEC 60079-15 requirements
and achieves a type of protection of at least IP54 (category 1) in accordance to
EN / IEC 60529.
This enclosure (control cabinet) must be labelled as follows:
WARNUNG – NICHT UNTER SPANNUNG ÖFFNEN
WARNING – DO NOT OPEN WHEN ENERGIZED
Note: If a potentially explosive atmosphere has been precluded, work can be also
performed when the device is under voltage.
The enclosure (control cabinet) in use must be able to safely dissipate the generated heat.
The H 7033 device has a power dissipation of 9W.
Since the device is equipped with exchangeable fuses, an additional warning must be placed
on the front plate of the enclosure (control cabinet). The warning should have following text:
WARNUNG – SICHERUNGEN NICHT UNTER SPANNUNG
HERAUSNEHMEN ODER WECHSELN
WARNING – DO NOT REMOVE OR REPLACE FUSES
WHEN ENERGIZED
The EC Directives and the following standards must be observed when installing and
operating the device:
DIN EN 60079-15 (VDE 0170/0171 Part 16)
DIN EN 60079-0 (VDE0170-1)
DIN EN 60079-11 (VDE0170-7)
DIN EN 60079-14 (VDE 0165 Part 1)
The H 7033 device is labelled with the following special product marking:
µII 3 G Ex nA II T4 X 0°C ≤Ta ≤60°C
Special conditions X must be regarded!
