7.1 Checks prior to start-up
7.2 Configuring the current output
The default setting for the current output is set at 4 to 20 mA.
The following applies to devices without Ex-protection for operation in zone 2:
The signal can be configured in "active" or "passive" mode. The current setting is specified in the order
confirmation.
The following applies to devices for operation in zone 1:
For devices designed for use in Ex-zone 1, the current output cannot be subsequently configured.
The desired configuration for the current output (active/passive) must be specified when the order is
placed.
For the current output version (active/passive), see the identification marking provided in the device's
terminal compartment.
If the signal is configured in "active" mode, no external power may be supplied to the current output.
If the signal is configured in "passive" mode, external power must be supplied to the current output, as
with the pressure and temperature transmitters.
IMPORTANT (NOTE)!
There is the additional document "JUMO flowTRANS MAG S/H - Safety Manual Ex for devices 406012 -
406019" for the measuring systems that are used in potentially explosive areas.
The information and data contained in the document must also be strictly observed.
IMPORTANT (NOTE)!
The following points must be checked before startup:
•
The voltage supply must be switched off.
• The voltage supply must match the specification on the nameplate.
• The pin assignment must correspond to the connection diagram.
• The sensor and transmitter must be grounded properly.
• The temperature limit values must be observed.
• The transmitter must be mounted at a location that is largely free from vibrations.
• The case lid and its lock must be sealed before switching on the voltage supply.
• For devices with a remote mount design and an accuracy of 0.2 % of the measuring value, make
sure that the sensor and the transmitter have the correct assignment: sensors have the last digits
X1, X2, etc. printed on the nameplates: transmitters have the last digits Y1, Y2, etc. printed on the
nameplates; devices with the last digits X1/Y1 or X2/Y2 belong together.
• Unused screw connections must be sealed with the provided plugs according to IEC 60079 prior to
startup
