Smart Alarm 12
Heater Failure Annunciator
|
Smart Alarm 12 is a micro controller based 12
window Annunciartor.This annunciator allows for field programmability of operating
sequence(Auto Reset ,Manual Reset ,First Up and Ring Back) ,grouping Trip / Non
Trip and NO / NC fault input through DIP switches avoiding hard wiring at the site.
This system is designed to sense the current through
heating elements continuously and raise an alarm if current is found to be absent
through anyone of the elements and exactly indicate which one is faulty. Our system
also can take care of avoiding false alarm while the heaters are switched OFF by
an ON/OFF controller. IR Bulb Failure Annunciator
In certain applications like semiconductor wafer
fabrications, infrared bulbs [IR bulbs] are heavily used. There will be too many
rejections if these bulbs fail during the process. It is required to have a system
which will immediately sense fusing of these bulbs and give alarm without waiting
for the temperature to fall. This is exactly like Heater Failure Annunciator with
slight modification and tuning.
Thyristor fuse Monitoring System
It is used to monitor 48 fuses, potential free microswitch
contact which are in series with each thyristor device. The status of the fuses
(whether fuse is intact, blown or disabled) are displayed on a graphic 320 x 240
pixel LCD module.
The faults (latest 64 ) are recorded in the non volatile memory with date and time stamped along with Project name , Fuse ID, Fuse Description downloaded by the user. These stored records can be printed through a serial printer. There are 6 feather touch keys on the front panel to give Print command to print faults and Fuse map, to set Time/Date, to configure fuses (Enable/disable, NO/NC contact), to configure serial port baud rate, to set password etc. There are 4 Relay Outputs. The 2 relays for Alarm output which are activated when any one fuse blows in any of the banks (one relay is redundant). Other 2 relays for Trip output which are activated when more than one fuse blow in any of the banks (one is redundant).
