H302x regulators
with relay outputs
PRODUCT DESCRIPTION
Programmable regulators with relay outputs are designed to measure temperature and relative humidity of air in non-aggressive
environment, to alarm indication and to control of external devices. Regulators are available in wall-mount and duct-mount versions or
with probe on a cable. For measuring temperature and relative humidity of compressed air is used type HxxxxP.
Two output relays functions can be set from regulator keyboard or from computer. Each relay can be assigned to one of measured or
computed value (dewpoint temperature, absolute humidity, specific humidity mixing ratio and specific enthalpy). Setting of delay,
hysteresis, audible alarm is enabled for each relay. Measured and calculated values are displayed on a two-line display. Using TSensor
software (see www.cometsystem.cz/software.htm) can be all regulator parameters set. To connect to PC is used USB adapter SP003
(optional accessories).

INSTALATION AND OPERATION
The mounting holes and connection terminals are accessible after unscrewing the four screws in the corners of case and removing the
lid. Devices have to be mounted on a flat surface to prevent its deformation. Pass cables (external diameter 3 to 6.5 mm) through
released glands and connect wires according to diagram. Wire cross-section choose from 0,14 to 1.5mm2. Tighten glands and screw the
lid. Insert attached plug into unused cable glands too. Pay attention to device mounting, because incorrect choice of working position or
place of measuring could adversely affect accuracy and long-term stability of measured values.
Actual parameters settings of each relay can be displayed by pressing of „ ▲“ key. To change any parameter, press the „Set“ key, enter
password (default 0000) and set required value. Then click on „Set“ and pressing „Esc“ key exit setup mode. To change the password
and to set all other parameters (alarm settings, used units, computed value selection etc.) is used Extended setting mode (see manual
for devices at www.cometsystem.cz/manuals.htm).
Devices don´t require special maintenance. We recommend you periodic calibration for measurement accuracy validation.
ERROR STATES
Device continuously checks its state during operation and if an error appears, it is displayed relevant code:
Err 0 –it is a serious error, please contact distributor of the device
Err 1 –measured or calculated value is over the upper limit
Err 2 –measured or calculated value is below the lower limit
Err 3 –it is a serious error, please contact distributor of the device
Err 5 –there is problem with assigned value to output relay
Err 6 –there is problem with assigned value to output relay
Err 9 –inserted password is not valid
SAFETY INSTRUCTIONS
- Humidity and temperature sensors of the regulator can not be operate and store without a filter cap.
- Temperature and humidity sensors have not to be exposed to direct contact with water and other liquids.
- It is not recommended to use the humidity regulators for long time under condensation conditions.
- Take care when unscrewing the filter cap as the sensor element could be damaged.
- Don’t connect or disconnect devices while power supply voltage is on.
- If the sensing probe of H3021P regulator is installed, make sure that measured area is without pressure.
- Installation, electrical connection and commissioning should be performed by qualified personnel only.
- Devices contain electronic components, it needs to liquidate them according to currently valid conditions.
- For more information, please use detailed manuals and other documentation which are available at
