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.

Index revision : C 7 6209

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 kV . For a high voltage unit on which the maximum voltage is below 100 kV , the
adjustment point is automatically reveled at its maximum value.

3.5.2. Control of Vm and Im outputs
Copies of Vm and Im are only given as indications. They are not calibrated inside the GNM and differ­ences can exist.

3.5.2.1. Control of the Vm output
The Vm scale is 0-5 V for 0-100 kV . The minimum impedance of the measure equipment has to be 50
k 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:

or :

1 Inside GNM
2 + 15 Vdc; 50 mA max

10 to 13 GNM case

Index revision : C 8 6209

3.5.3.2. Using external voltage
The external voltage is between 12 and 24 Vdc.
Input impedance roughly 1 k Ω .

0 V Supply return 12 to 24 V

1 Inside GNM
2 + 12 to 24 V dc

10 to 13 GNM case

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 P8 = 1,
The trigger has to be connected as follows:

1 Inside GNM
2 + 15 Vdc; 50 mA max

10 to 13 GNM case

Index revision : C 9 6209

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.

2 OK board
3 No OK board

4. Operating principle of the GNM 100

4.1. Supply voltage and connections

The voltage of the GNM 100 is preset at 220 V. Make sure that the earth terminal of the module (located
at the back) is property connected to the earth with cable with a gauge between 6 and 10 mm2. Connect
the mains cord. Connect the gun plug to the GNM 100 (marked A on the back of the box).

WARNING : The messages indicated are given as guidelines and vary according to the type of
gun used.

4.2. Automatic selection of the high voltage unit

WARNING : Each time a new type of high voltage unit is validated, all the parameters take the
works preset value and the old parameters are replaced by the new ones.

When connected to a different type of high voltage unit, the GNM message will request validation of this
new high voltage unit which is done by pressing key 4 .
When connected to a high voltage unit, the GNM 100 automatically recognises it and displays its name
on the screen. If it is the same as the one used the last time, the following screen will not appear.

If the display indicates a type of gun other than the one connected, do not validate. Switch off the GNM
100 and disconnect the gun. Connect the gun again and try to power the GNM 100 again.
If the gun is still not recognised by the GNM 100, contact a SAMES distributor.

After validation, the display indicates:

•U = 0 (high voltage set point)

•I = 80 (current limitation set point).

Press key 4 (see § 2.1 page 4).

4.3. Modifying a set point

To change the high voltage set point, press key 2 or 3 . The display will, for example, indicate:

Press V to scroll the menu.

Index revision : C 11 6209

To change the current set point, press key 2 or 3

. The display will, for example, indicate:

4.4. Storing the set points

The GNM 100 can memorise 9 U and I value tables preset by the user as needed. These tables are ref­erenced from J1 to J9.
To create a table:

• The gun trigger must be released.

• Adjust the high voltage (Vc) and the current limitation (Il) set point values according to the proce-

dure described in paragraph3.3, then press key .

the display will, for example, indicate:

•Choose a table (from J1 to J9) by pressing keys 2
or 3 (for example J2).

•Press key for three seconds. The U and I values

are stored in the table J2.

4.5. Using the values stored

When, for example, the display indicates:

Choose a table (from J1 to J9) by pressing keys 2

or 3 .

The set point values of the high voltage and the cur­rent limitation used are memorised in the table cho­sen.

4.6. Triggering the high voltage

The trigger has to be puller for the gun to be powered.
The display takes the form of a bar graph, indicating the high voltage and current values, for example:

Displayed at the end of each bar graph is the volt­age value at the gun electrode (in kilovolts) and the
current debited by the gun's high voltage electrode
(in micro amps).

The position of the symbol (*) at the end of the bar graph indicates whether the module works by a high
voltage regulation or by a current limitation.

If no table is used when the trigger is pulled, the high voltage and current set point values can be modified
by pressing keys 2 or 3 .

If a table from J1 to J9 is used when the trigger is pulled, the values cannot be changed.
When the trigger is released for more than 3 seconds, the last value read is displayed.

Index revision : C 12 6209

4.7. Faults

Six "major" faults can be displayed on the GNM 100

Fault tempeture Excessive casing temperature
Fault UP High voltage unit not recognised
Fault CC Low voltage output short circuit
Fault Reg. Freq Bad frequency regulation
Fault µP Micro calculator fault
Fault Supply Bad internal supply regulation

The faults are displayed in code on the two display lines and the red signal light lights up.
The only way to reset the faults is to turn off the module for a minimum of 30 seconds and to put it on

again by means of the push button (7).
The GNM 100 has a safety sector which removes the display messages when activated.
To reset, turn power off (7). Wait one minute and turn on again (7).

4.8. Cleaning the GNM 100

WARNING : turn off the GNM 100 control module before cleaning

To clean paint from the front of the GNM 100, use a rag dipped (and not soaked) in ethyl alcohol or
burning alcohol.

Note: Do not use a solvent or a thinner.

Dry immediately with a clean cloth.

5. Spare parts
