Introduction
3.4 UNPACKING AND INSPECTION OF SCANNER
G-Tek Scanner are dispatched in a recyclable, environment friendly package specially designed to give
adequate protection during transit. If the outer box show sign of damage, it should be opened immediately
and the scanner be examined. If there is evidence of damage, the instrument should not be operated and
the local representative contacted for instructions. Ensure that all accessories and documentation is
removed from the box. If the scanner is for immediate use, you can start installing it now as per following
instructions. Please preserve the original packing along with all internal packing for future transport
requirements.

4.1 ELECTRICAL INSTALLATION
4.1.1 General information
To comply with Underwriter Laboratories (UL) and Canadian Standards Association (CSA) certification, route
signal leads and power cables in earthed (grounded), flexible metal conduit.
Connect proper Earth to the earthing terminal of the scanner.
Instruments not fitted with the optional internal on/off switch and fuse must have a disconnecting
device such as a switch or circuit breaker conforming to local safety standards fitted to the final
installation. It must be fitted in close proximity to the instrument within easy reach of the operator
and must be marked clearly as the disconnection device for the instrument.
Remove all power from supply, relay and any powered control circuits and high common mode
voltages before accessing or making any connections.
Use cable appropriate for the load currents. The terminals accept cables up to 14AWG (2.5mm1).
The instrument and all inputs and outputs conform to Mains Power Input Insulation Category ll.
All connections to secondary circuits must have basic insulation.
After installation, there must be no access to live parts e.g. terminals.
Terminals for external circuits are for use only with equipment with no accessible live parts.
If the instrument is used in a manner not specified by the Company, the protection provided by the
equipment may be impaired.
All equipment connected to the instrument's terminals must comply with local safety standards (IEC
60950, EN601010-1).
NOTE:
In order to ensure maximum recorder performance, proper wiring installation practices must be followed.
Failure to do so can result in a range of problems, from loss of configuration to component failure, caused
by transmitted or radiated electrical noise. Proper consideration must be given to local noise sources and
appropriate suppression steps taken to minimize any potential problems. Among the most common sources
of noise are: Relays, SCRs, valve solenoids, electric motors, power line disturbance, wire-to-wire coupling,
electrostatic discharge (ESD) and radio-frequency interference (RFI).

4-11 G-Tek Corporation
Installation
To achieve the best results, the following notes should be considered:
1. Low level signal wiring such as that associated with thermocouples, RTDs and current loops should
always be kept separate from power and control output wiring.
2. Signal input wiring should be twisted pairs/triplets etc. The conductors should be stranded rather
than solid in construction. All signal wiring should use ground-shielded wires, or be routed through
grounded conduit to minimize the effects of RFI and ESD.
3. Special care should be taken when wiring to relay or solenoid coils, as large transients are produced
when coils (or any other inductive loads like motors or arc welding equipment’s etc.) are switched.
This problem can be eliminated by the use of suitable suppression devices across the coil. Coil
transients can also be transmitted through the air, so the recorder itself should be mounted as far
as possible from power control devices and/or wiring.
4. When line power is poorly regulated and / or subject to voltage surges or transients, consideration
should be given to the use of a line conditioning/transient suppressing line power regulator. Process
control motors, valves, relays and heaters should not be connected to the same power lines that
are used for instrumentation.
5. The connection of the scanner to a proper safety earth ground is essential. Such a connection not
only reduces the possibility of electric shock, but also provides the required return for the scanner
line power filters.
6. All local electrical codes of practice must be followed when installing any instrumentation.

4.1.2 Wiring diagram for scanner series sc5x9x
Check for proper Earthing:
Proper Earthing is necessary for best performance of the Scanner. Follow the steps mentioned below to
check whether the earthing given to the scanner is proper or not:
Find out the Phase line of connection with the help of “Tester with Neon Lamp”. When Neon Lamp
glows, it is an indication of the phase line.
Once Phase is found, the other hole which is in line of phase is the Neutral line.
The third hole which is apparently bigger in diameter is the Earthing line.
Now take the voltmeter with appropriate measurement range (normally 7SOVAC or higher) and put
the probes into PHASE and NEUTRAL line and take reading.
The voltage across PHASE and EARTH, and NEUTRAL and EARTH.
The voltage between Neutral and Earth Should not be more than 6V. If by any chance it is more than
30V, it is a serious fault on earth line. And must be immediately be corrected.
Proper Earthing is essential for safety of the personnel and also for the proper functioning of the
equipment.
Note: If connecting the instrument in the panel, panel and scanner both should be at the same earthing
potential.
Wiring diagram for scanner:
See the back panel of the scanner, you will find all the connectors for wiring. As shown in the following
figure.

Mains supply connection
The connection for Mains supply is shown in figure 5. As per the figure the live, neutral & earth from the
mains cord are connected to L, N & E respectively. Ensure that the bared ends of the mains cord are fully
inserted into the mains connector and no loose/poor connection.

Installation
For sensor wiring, all the sensor connectors are at the back side of the scanner as shown in Figure 6.
Figure 6- Sensor Wiring
The Scanner can be connected and configured to operate with a variety of signal sources as thermocouple,
RTDs, dc current, dc voltage etc. The sensor wiring for different sensors is shown as below:

Installation
Sensor wiring - RTD (Pt-100) 3-wire input
Figure 7- Sensor Wiring - RTD (Pt-100) 3-Wire Input
The connection for 3-wire RTD (Pt-100) sensor is shown in figure 7. Normally RTD (Pt-100) sensor with 3-
wires has two similar color wire and other one different color. Connect two similar color wires at ‘-‘and ‘G’.
Connect the remaining dissimilar color wire at ‘+’. Similarly connect for all other channel.

Installation
Sensor wiring –RTD (Pt-100) 2-Wire Input
Figure 8- Sensor Wiring - RTD (Pt-100) 2-Wire Input
For 2-wire RTD (Pt-100) sensor connect 2-wires of the sensor at ‘+’ & ’-’and put an external short link
between ‘-‘and ‘G’ as shown in figure 8. Similarly connect for all other channels.
Notes:
1. When wiring RTDs, lead length and diameter must be chosen such that lead length are equal and
that each lead exhibits no more than 10 ohms resistance between the scanner and the RTD (Pt-
100).
2. For Input connections, high quality, low resistance contacts must be used which are suitable for dry
operations.
