2.   The  Electrical  Connection

l  The power supply voltage:


(4~20)mA/HART   (Two wire system)       The power supply and the output current signal sharing a two core   shield cable. The supply voltage range see technical data. For intrinsically   safe type must be a safety barrier between the power supply and the   instrument.
(4~20)mA/HART(Four wire   system)       Separate power supply and   the current signal, respectively using a two-core shielded cable. The supply   voltage range see technical data.
RS485 / ModbusPower   supply and Modbus signal line are separated, respectively using a two-core   shielded cable, the power supply voltage range see technical data.

Explosion Proof Connection

The intrinsic safety version sensors (Exia IIc T6) use Alu-die casting housing and filling Silicone rubber sealants internal structure aimed to prevent sparks resulted from circuit failure from leaking out. It is applicable for the continuous level measurement of flammable medium under Exia IIc T6.

A safety barrier FBS-2 must be used together with the intrinsic safety instrument. It is an associated device to this product for the power supply of this product. The main specification is intrinsic safety: Exia IIC, voltage of power supply: 24V DC±5%, short-circuit current: 135mA, operating current: 4...20mA.

All cables must be shielded. The max length is 500m for the cable from the barrier to the sensor. Stray capacitor0.1μF/Km, stray inductance 1mH/Km. Instrument must be connected to the ground potential. Any unapproved associated device is not allowed to be used.

3.   Programming and  Debugging


l  There are three kinds of debugging method:

1)     Display / Keyboard  

2)     Host debugging  

             3)    HART handheld programmer

      l  Display / Keyboard:

Please debug the instrumentation by four buttons on the display screen. There are three debug menu languages optional. After debugging is generally used only for display, through the glass window can read measured value very clearly.
