masibusif group mode is selected as 1rELy, then Relay action type ( ON or OFF ) for alarm limit 1 is only programmable. Latching for LED Status of alarm limit 1 and alarm limit 2 is programmable. Scan time is programmable up to 99 seconds. Provision for zero and span setting is made to restrict range of usage and programming. This restricts accidental wrong setting of set point beyond the range of interest. Outside this range the unit will indicate data as 'OVER' towards span side up to 5% more than programmed span and UNDR towards zero side up to 5% less then programmed zero. This zero and span setting is more useful for linear inputs for setting the range between 1999 to 9999 counts. Digital input is mapped on 0-5V input and printing output and display is as ON if input voltage is less than 2.5v DC and OFF if input voltage is greater than 2.5v DC. The reverse feature can be obtained on using UPSCALE/DOWN SCALE of open sensor. There is no relay or any output action for digital input. Number of optional features provided including Relay output, Open collector output, Isolated Retransmission output, Serial printer output or Centronics printer output which can be easily set through front panel keys under Auxiliary Slot1 and Slot2 configuration. Full relay mapping possible. Any channel can be assigned to any group. For each group two relays are given for one alarm limit 1 and second alarm limit 2 if relay group mode is selected as 2rELy. For each group one relay is given for alarm limit 1 if relay group mode is selected as 1rELy. Isolated Retransmission output (420mA) can be configured for either Minimum or Maximum of channels selected in a group. Serial Communication with RS 232 / RS 485 is also provided for using the scanner as backend for Supervisory Control or for P.C. connectivity. Standard protocol for communication used is MODBUS-RTU.Page 3 of 52

1. TECHNICAL DETAILSThis is a versatile micro-controller based Scanner with a very high performance to price ratio. The features offered in this product are better than any other Scanner available in similar price range. The instrument is made in 96x192x208 mm size with standard cut out of 92x188 mm. Front is sealed membrane type to withstand dusty environment. On back plate PCB soldered flat terminals of very good quality are used. The programming, calibration and operation of the instrument are by nine simple keys with two independent displays for channel no. and data value for that channel. Channel display is of two digits to differentiate it from data display of four digits, each of 0.56" seven segments LED. Status of Run/ Program/Verify mode, Fault, Auto/Manual mode and status of each channel for programmed set point limits are displayed by 3 mm red LEDs. Operation of the instrument is menu driven with user understandable prompts. Provision for PASS WORD is kept for unauthorized access to critical configuration and program parameters. The product is made to accept all 7 standard thermocouple, PT100 RTD, CU-53, PT46, Linear voltage and current inputs and digital input. The type of input can be changed in field also. The calibration of the unit is done without trim-pots. The unit can be calibrated in installed condition itself by front panel keys at any given point i.e. user do not required to feed a fixed signal. RTD inputs are linear for 0.1 deg. as well as 1 deg. resolution. Also incorporating Self check feature for stand alone verification of hardware of the device of input section. Set point type (LL, HL or HH), abnormal status (Alarm or Trip) for alarm limit1 and alarm limit 2 as well as Relay action type (ON or OFF) for alarm limit 1 and alarm limit 2 are programmable if group mode is selected as 2rELy. Relay action type (ON or OFF) for alarm limit 1 are programmable if group mode is selected as 2rELy.
