This is micro-processor based Donnelly Chute level indictor Transmitter with isolated o/p(4-20 mA), 10nos digital optical o/p and 2 relay control .The instrument is field programmable and user friendly. In this Instrument user can be  set sensor sensitivity , sensor level selection, sample delay time and relay set point etc. The user can be set level 2-10 then instrument automatically tune for o/p 4-20 mA and display 0-100%, The instrument  have five settable parameters like rL1, rL2, snt, trl, Lst. The Instrument read input level in sequence 1 to 10 if misplaced any level then it will not show above levels.

Parameters :

• Snt : Sensor Sensitivity  adjustment
• Lst : Level Sensor selection (2-10)
• Trl  : sample Delay adjustment
• RL1 and rL2 : Relay set point (0-100)

SNT(sensitivity adjustment Parameter) :In this parameter user can be adjust sensitivity of every (1-10 sensor) level sensor through key pad. The sensor value can be set in this parameter 93(Max.) to (185min.) sensitivity and it is normaly set 100 value of every sensor. If SNT value  set 93 then direct on without input connection. 

LST (level selection parameter)

• The user can be set input level 2-10 then instrument automatically tune for o/p 4-20 mA and display 0-100%
• Trl : 20 set
• rL1, rL2 : Relay set point value

Specifications :

• Main (auxiliary supply) : 220vAc +-15% @50 Hz
• O/P (Analog) : Isolated 4-20mA
• O/p (digital)  : Optical digital output (op1 to op10)
• Relay set value :  000-100 settable
• Display range : 0-100% according select sensor level (2-10) settable
• Time delay setting : 001-100 ms settable
• Input : 10nos. Probe sensor (digital i/p)
• Digital i/p / o/p : Indicate by LED as fitted on the front panel
• LED : Red Led for i/p , Green Led optical digital o/p
• Control Relay : One pair normally  
• Open potential free contact : @ 5A at 240v AC  
• Overall size : 96x194x223 mm (WxHxD )
• Panel cutout : 184X92mm(HxW)

This is micro-controller based RPM Transmitter with 2 Relay control output. It is designed for settable  teeth or pulse(1-99) PNP/NPN type photo sensor or proximity sensor input.   User can be adjusting range parameter for required retransmission output (4-20mA) otherwise o/p can be higher than 20mA.The instrument can be display over (over range) message when rpm greater than 9999.
The manual covers all aspects of operation of the instrument. Please read instructions carefully before operating it.
