1. General information for installation and operation
Identification in accordance with Guideline 94/9/EG:
0158 II (1) G
device group
intrinsically safe equipment with external circuits
for connection for category 1 devices
for explosive mixtures of air and flammable gases,
steams or vapours
Identification of explosion protection:
[Ex ia] IIC
assosiated electrical equipment in
accordance with European standards
explosion protection
equipment group
Safety instructions:
If it is assumed that safe operation is not longer possible, the device must be taken out of service and secured
against accidental operation.
Reasons for this can be:
visible damage of the device
failure of electrical function
longer storage at temperatures over 85°C
heavy transport stress
Before the device is put back into operation, a professional routine check must be performed in accordance
with DIN EN 61010, Part 1. This examination should be made at manufacturers
’ side. Repair work at ex-
devices may be accomplished only under attention by §9 of the ex regulation (Elex V).
Devices with intrinsically safe circuits may be never operated in not-intrinsically safe circuits. If ex devices in
not-intrinsically safe circuits are operated, these need to be marked particularly and the ex labels must be
removed absolutely, so these devices do not find use for intrinsically safe electric circuits later again. A later
check of the devices on observance of the conditions for the explosion protection is possible with a
disproportionately high expenditure only and is rejected therefore usually.
Proper use
The MTP200i..-E transmitter can be used for exact measurement of temperature with a Pt100 sensor or a
thermoelectric couple in Ex-area. Two additional inputs for an own safe current or voltage signal enlarge the
use of the assembly to the receiving multicoupler.
The Pt100/slide-wire sensor at the contacts d28, z28, d30 and z30 corresponds the explosion protection
„intrinsic safety“ category for "ia" or "ib".
The thermoco
uple/mV input at the contacts d32 and z32 corresponds the explosion protection „intrinsic safety“
category for "ia" or "ib".
The +/-20mA-input at the contacts d24 and d26 and the +/-10V-input at the contacts z24 and z26 corresponds
the explosion protection
„intrinsic safety“ category for "ia" or "ib".
