Memocheck Sim CYP03D Basic safety instructions
Hauser 7
‣
Before commissioning the Memocheck Sim CYP03D, make sure that the battery
compartment is closed securely with a screw.
‣
The maximum permissible cable length is 100 m (330 ft).
‣
Pay attention to the requirements for electrical installations in explosive atmospheres
(EN/IEC 60079-14).
‣
The conductive protective coating on the device is part of the Ex-related safety concept.
Make sure that there is no damage >4 cm
2 to the protective coating.
Hazardous area versions of digital sensors and simulators incorporating Memosens
technology are indicated by a red-orange ring on the plug-in head.
IECEx
Connecting the approved digital Memocheck Sim CYP03D sensor simulator to the IECEx-
certified, intrinsically safe sensor output circuit of the Liquiline M CM42 (IECEx TUR
11.0007X) transmitter or alternatively to an IECEx-certified, intrinsically safe Memosens
sensor output:
Use only the following IECEx-certified measuring cables:
– CYK10-G*** (IECEx BVS 11.0052X)
– or a Memosens measuring cable that has IECEx certification and is identical in terms of
design, appliance technology and function.
‣
The electrical connection must be made according to the wiring diagram.
‣
The transmitter's Memosens input must support the following maximum values. In
particular, the effective inner inductance and the capacitance of the approved, intrinsically
safe sensor output may not exceed these values:

ATEX
Connecting the approved digital Memocheck Sim CYP03D sensor simulator to the ATEX-
certified, intrinsically safe sensor output circuit of the Liquiline M CM42 transmitter or
alternatively to an ATEX-certified, intrinsically safe Memosens sensor output:
Use only the following ATEX-certified measuring cables:
– CYK10-G*** (BVS 04 ATEX E 121 X incl. amendments)
– or a Memosens measuring cable that has ATEX certification and is identical in terms of
design, appliance technology and function.
