Detailed Product Description
The Tank Side Indicator or Local Readout provides a data readout at thebase of tank with roof mounted gauges or side mounted gauges. Itdisplays a data of LEVEL, TEMPERATURE, ALARM STATUS & SERVO CHECKif servo gauge is provided.
PRINCIPLES OF OPERATION
It'stwo data loop wires may each be connected in series with the two dataloop wires of the Digital Transmitter, hence listening to same datathat is transmitted by the Transmitter to the control room.Alternatively the local readout can be set in loop 2 of the Transmitterin call mode, providing dual circuit & system 'Back up'.
The readout station can be set to operate in one of the three modes
Receive Only : i.e. monitors any communications between the transmitter & the receiver in the control room.
Test mode : Checks liquid crystal display & operates in the Receive Only mode.
Transmit& Receive : This enables the operator to request information fromthe Transmitter by calling a particular task, & read the datareceived on the display.
It also provided as an option, two relayoutputs which echo two of the four alarm switch inputs of theTransmitters & can therefore be used to locally interlock valves& pumps etc.
