1. Introduction

WARNING : Safety warning: the GNM 100 must never be installed in an explosive atmosphere.

This means it must be installed outside the coating booth at a minimum distance of 1.5 meters

(5 feet) from the nearest opening.

This control module is for the power units hereafter called the "high voltage units" which are fitted inside

the guns. This module is only for use with guns made by SAMES.

• The GNM module has a conductive extruded aluminium (black anodize) box, the tightness of

which conforms to protection index IP 64. Two part numbers are available:

• 858075 for all countries except the United Kingdom.

• 1516137 for the United Kingdom.

WARNING : For a use in cabinet, the room temperature must be below 45°C.

We strongly advise you not to place the GNM close to any source of heat, which would increase

its inner temperature and engender a working defect.

However, if the GNM has to be located in such conditions, provide for an air conditioning device.

The maximum temperature is 45°C for a use with a 90 KV/ 100µA high voltage unit (HVU). This

maximum temperature depends on the supplied power, therefore on the type of HVU/sprayer

which controls the GNM.

Storage temperature: 0°C to 70°C.

3. Low voltage connections

3.1. Supply

The

GNM

can be supplied with 220 V or 110 V voltage, 50-60 Hz. Selection takes place by means of a

switch located on the main printed circuit.

3.2. Low voltage connectors

WARNING : see RT Nr 6169 for use with a high voltage unit UHT 153.

3.3. Connecting plug (12 pins A)

Connection to the high voltage unit.

3.4. Connecting plug (7 pins C)

Connection to the controls of the atomizer (e.g. electro valve). It is possible to use the 4, 5 and 6-pins

(trigger copy for the PLC).

WARNING : This relay is for passing low currents. If a high current is used this contact can no

longer be used for low currents.

3.5.1. Analog input

Cabling on external adjustment points can be 4/20 mA or 0-10 V.

3.5.1.1. 4/20 mA adjustment point

This scale setting has to be done in a PLC. To do this, apply an adjustment point of 8 mA and another

adjustment point of 16 mA and read the HV value on the

GNM

screen. A simple calculation permits one

to fine the corresponding point.

3.5.1.2. 0/10 V adjustment point

Scale setting is done inside the

GNM

10 V corresponds to 100

. For a high voltage unit on which the maximum voltage is below 100

, the

adjustment point is automatically reveled at its maximum value.

3.5.2. Control of

and Im outputs

Copies of

and Im are only given as indications. They are not calibrated inside the

GNM

and differ-

ences can exist.

3.5.2.1. Control of the

output

The

scale is 0-5 V for 0-100

. The minimum impedance of the measure equipment has to be 50

Ω

3.5.2.2. Control of the Im output

The Im scale is 0-5 V for 0-500 µA.

The minimum impedance of the measure equipment has to be 50 k

Ω

3.5.3. Wiring of external trigger

Control of the external trigger can be done in two ways:

• Dry contact,

• Using external voltage between 12 and 24 Vdc (see § 3.5.3.2 page 9).

3.5.3.1. Dry contact. There are two possibilities:

3.5.3.2. Using external voltage

The external voltage is between 12 and 24 Vdc.

Input impedance roughly 1 k

Ω

WARNING : Inputs 10 and 13 are opto-coupled inputs. They are therefore isolated from the earth.

Make sure that the 0 V of the 12 to 24 V supply is at a potential close to the earth.

3.5.3.3. In the case where

= 1,

The trigger has to be connected as follows:

0 V Supply return 12 to 24 V

3.5.4. Using information relative to the faults

The closed contact of the OK board relay signals that the board is under voltage and that there is no fault.

WARNING : This relay is for passing low currents. If a high current is used this contact can no

longer be used for low currents.
