Donnelly Chute Level Transmitter, Packaging Type: PTFE, Model Name/Number: Dcl

Product Details

This is micro-processor based Donnelly Chute level 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 set sensor sensitivity, sensor level selection, sample delay time and relay set point etc. The user can set level 2-10 then instrument automatically tunes for o/p 4-20 mA and display 0-100%. The instrument has five settable parameters like rL1,rL2,snt,trl,Lst. The Instrument reads input level in sequence 1 to 10 if misplaced any level then it will not show above levels. Operations Manual – Donnelly Chute Level Transmitter with Modbus Communication Model M11 NX Operations Manual – Donnelly Chute Level Transmitter with Modbus Communication Model M11 MAX ParametersSnt: Sensor Sensitivity adjustmentLst: Level Sensor selection (2-10)Trl: sample Delay adjustmentRL1 and rL2 : Relay set point (0-100) snt(sensitivity adjustment Parameter) In this parameter user can set 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 normally set 100 value of every sensor. If snt set 93 then i/p led 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 setrL1,rL2 : Relay set point value Terminal DetailsS1 to S10 : i/p for probe type level sensorGND : Common terminal of probe sensor (Donnelly chute sensor)L1 to L10 :o/p for isolated digital out put to plc+24vdc : +v common (+24 vdc) for plc digital i/pO/p 4-20 mA : mA output (isolated)P : common terminal of RelayN/O : Normaly open terminal of RelayN/C : Normaly close terminal of relayL : Phase of 220v AC @50/60HzN : NeutralE : Earth Specifications Main (auxiliary supply) : 220vAc +-15% @50 HzO/P (Analog) : isolated 4-20mAO/p (digital : isolated digital output (L1 to L10)Relay set value : 000-100 settableDisplay range : 0-100% according select sensor level (2-10) settableTime delay setting : 001-100 ms settableInput :10nos.

If you do not want to change in this parameter then use only ENT key, if press only ENT key it means by pass snt parameter, if press PRG key and ENT key it means modified value stored and display snt for next level sensor sensitivity calibration And same process apply for level 1 to level 10 after that, Next parameter Lst display press ENT key display last level select if change (2-10) then use up/dn key press ENT key display trL press ENT key display last value and set 20 and press ENT key and now exit configuration mode.
