Controls and Installation
3.1
Electrical Installation
The ISR 12-LO/GS is powered by a voltage of 24 V DC or AC. The length of the 24 V supply line
should not be longer than 30 m. Hence the use of 24 V site internal supply network is also not
recommended. This length restriction does not apply for the analog and digital signal lines.
As the instrument is operating with heated and thermostatically controlled sensors, it needs a
warm-up of up to 5 minutes (during this warm-up period the LED display indicates “7777“),
after that the instrument is ready for use. To switch off the instrument, interrupt the power
supply or unplug the electrical connector.
To meet the electromagnetic requirements (EMV), a shielded connecting cable must be used.
The shield of the connecting cable must be connected only on the pyrometer side to avoid
ground loops.
IMPAC offers connecting cables, they are not part of standard scope of delivery. The main
connecting cable has wires for power supply, interface, analog output, external laser switch and
external clear of maximum value storage via contact (see section 8, Reference numbers) and
12 pin connectors. The cable includes a short RS232 adapter cable with a 9 pin SUB-D connector
for direct PC communication. This adapter is not used in combination with RS485 interface.
Attention:
When connecting the power supply, ensure the polarity is correct.
