1 Security
1.1 Precautions for use
Please always use the device in compliance with the intended use and in the limit of described parameters in the technical
features in order not to compromise the protection ensured by the device.
•The device must be connected on a low voltage installation in compliance with the regulation of the country where
the device is installed (in France: NFC 15-100 .
•Every fuse replacement must be realised with the switched off device by using a recommended fuse in the
documentation (see the technical features of the device: please see the technical datasheet .
•Disconnect the power supply cable to switch off the device.
•The device is not adapted for ATEX areas according to the current regulations.
1.2 Symbols used
For your safety and in order to avoid any damage on your device, please read the described
processes in this user manual and read carefully the notes preceded by the following symbol:

3 Operating
3.1 K3 display description
1 : OUT1 : pump of the wet air circuit in operation
2 : OUT2 : pump of the dry air circuit in operation
3 : - : value of the measured humidity is lower than the setpoint value
4 = : value of the measured humidity is stabilized at the setpoint value
5 : + : value of the measured humidity is higher than the setpoint value
3.2 Operating principles
The GH 500 is a device which allows to generate points of relative humidity on a range from 10 to 85% HR. It works on the
principle of a mix of moist air and dry air in different proportions, in order to obtain the required relative humidity value. For
the generator works optimally, it must be placed in the most stable room in temperature (between 20 and 25 °C . This
condition will dene the homogeneity in humidity of the generator. Once the generator is properly installed and turned on,
simply select the threshold value of the required relative humidity.
3.3 Enter a setpoint value
To enter a setpoint value :
➢Press on The screen starts ashing in displaying SP1 and the actual setpoint value.
➢Press on to increase the setpoint value or on to decrease the setpoint value.
➢Press on to validate.
➢Press on during 3 seconds to return to the normal display.
3.4 Performances
The stability of the GH500 regulation allows to have a regulated setpoint value at ± 0.1% RH. It is able to pass from 10 to
85% RH in 35 minutes and from 85 to 10% RH in 30 minutes. However, the durations can vary according to the
consumables wear condition, if the rise and fall times become more longer, verify their conditions.
The homogeneity in dry temperature is 0,1°C in a restricted volume, it is therefore advised in order to have a precise
measurement to put the probe in the middle of the housing.
3.5 Use advice
The measuring chamber must be always airtight. The ball of the overpressure control exhaust outlet (see 08 instrument
description chapter must turn when the pump is in operation.
If not, check that the front part of the measuring chamber is well closed and that the cable glands are well blocked.

4.1 Regeneration of the desiccant pearls
Before using the device, put a cotton lter at each end of the dessicant pearls tube.
The dessicant pearl is a material which allows to drain the air; the little balls pick up moisture: their colours pass from
orange to transparent. When the colour becomes transparent, the dessicant pearls absorption capacity is reduced and it
must be regenerated. One hour in an oven at a temperature of 100°C allows a proper recovery of their properties. However,
after several regeneration periods, their capacity can be degraded and it is necessary to change them.
4.2 Maintenance of the bubbler
The bubbler allows to load humidity in air. For an optimal operation, the level of water must be maintained. You must use
distilled water to avoid the stagnation and clean the bubbler if the water changes colour or becomes opaque. It is
important not to exceed the maximum level indicated at risk of see the water overowed from its tank and inltrate the
pneumatic circuit.
