1.1 – GENERAL DESCRIPTION
TT 73 is a programmable microprocessor based timer with 1or 2
outputs.
The instrument offers the possibility to program: up to 3 set points
time, 5 operating modes for the output OUT1, 4 operating modes for
the output OUT2, 4 time scales (from 9999 hrs. maximum to 0.1
sec. minimum), 4 functioning modes of counting enable and 2
counting modes (UP or DOWN).
The instrument can have an inside back up battery (optional) which
permits the counting also without power supply.
The counting state is visualised on 4 digits display while the outputs
state is signalised by a led.
The instrument can have 2 outputs (relay or to drive solid state
relays) and 2 digital inputs for count enable (CNT EN) and reset
(RES) which can be for free voltage contacts or voltage signals (the
same voltage supply value).
The programming of the instrument is possible by means of the 3
keys placed on the front while the counting is possible using the
frontal key START/STOP or using the back inputs CNT EN and
RES.
