The TC5+ is a remote monitoring system
previously manufactured to test the correct working of all installed
equipments inside of a TV repeater room situated on the top of a mountain. It
can be also used for several other applications.
The TC5+ is composed by a transmitter and a receiver equipment.
The system send DTMF bi-tone information on the audio line and it allows to test
from remote the status of:
The channel used to control the environmental
temperature has got a pre-set up range between 15°C and 40°C.
By a simple process is possible to change rather the minimum value (between 0
and 45° C) than the maximum value (between 0 and 45° C) of the temperature
range.
Maximum and minimum temperature data are saved into a flash memory keeping this
information even when the supply is absent.
The transmitter DMTF is able is to point out the supply absence and send details
about this alarm; this operation is lasting about 30 seconds thanks to the
presence of two big capacitors able to provide the necessary energy for the
above mentioned time.

Obviously this alarm indicates that remote post
is working with an alternative energy source (battery or generator group) and therefore is necessary to send some technicians on the
place in order to solve the problem as soon as possible.
If the problem keeps unsolving the service will be stopped in a few time.
On the transmitter (remote post) there is an address selector that allows to
choose between different addresses (from 0 to 9) that it should necessary have
to coincide to the receiver DTMF address that receives data to be monitored.
On the back side of the transmitter are situated the clamp taking over the 5
external locks and the two XLR input connectors and the audio output and the
DTMF signal.
It's possible to insert into an audio input connector, a line signal coming from
a pre-amplified microphone to send vowel information to a control post (receiver).
Data are transmitted in a DTMF size every about 2 seconds and the receiver will
control the transmission attendance even if any alarm is on.
If an audio connection is interrupted or the receiver address it doesn't
coincide to the transmitter one, all the 5 flashing led will show the absence of
DTMF input data.
If one the 5 alarm channel is on, the receiver led will be on and the
acoustic alarm will utter an intermittent sound.
To deactivate this sound it's necessary to press the SETUP key and the alarm led
will pass from a fix state to a flash one state indicating the acoustic signal
deactivation.

The 5 led starting up meets the 5 relays that
will close all clamps output situated on the receiver back panel.
When the energy on the transmitter is faulty, the receiver will indicate it by
switching on the power down led and closing the relay on 1 and 2 connectors pin
with 4 contacts situated on the back panel.
After about 30 sec. the transmitter stops to send DTMF data and all receiver
leds will be flashing.
When the temperature sensor of the transmitter shows that the environmental
temperature is out of the set up range, the alarm will be sent to the
receiver, so the OVER RANGE TEMP will be lighted and the relay will be closed on
the 3 and 4 pin of the 4 contacts round connector situated on the back panel.
It's possible to put the audio output of several receiver into a loop
state, taking care that each single receiver has been placed to an
identification address, different from the other ones.
Both the transmitter and the receiver supply is of 220 Vac.
