1 SAFETY INSTRUCTIONS
A)Keep these Operating Instructions in a place where they can always be easily consulted by the operator or by
maintenance personnel.
B)Before making an intervention or connection of any kind, make sure that the mains are disconnected both from
the instrument and from any device connected to it.
C)Caution, there may be hot components inside the plastic instrument container.
D)No user-serviceable parts are inside the plastic instrument container.
E)DTI products and any other device connected to them must be installed in compliance with the safety
regulations in force.
F)Make sure that, whenever a transformer for instrument power supply is required, it complies with the safety
regulations in force.
G)DTI products are designed and manufactured in compliance with the safety regulations in force. Nevertheless, if
our products are not installed in accordance with the Safety Instructions, as well as the indications given in these
Operating Instructions, then this may cause a reduction of the safety level of our products. Furthermore, the
ambient operating conditions given in our technical data must be complied by, and in any case absolutely avoid:
water condensation or excessive humidity; exposure to steam, corrosive - or toxic gases, contact with any type of
liquid, and exposure to shocks or to extreme vibrations. Not respecting the above indications could cause
malfunctioning and unpredictable consequences, e.g., in the worst cases malfunctions that could cause dangerous
electrical discharges on probes or other parts.
H)DTI products are guaranteed for a specific level of immunity against electromagnetic disturbances in
compliance with EC regulations. We would like to call to mind that electromagnetic disturbances can be either
irradiated and/or conducted. By irradiated electromagnetic disturbances we recommend to screen the
instruments with a metallic screen connected to ground. To eliminate, or at least reduce conducted
electromagnetic disturbances, that do not only propagate through the power supply, but also through probes or
connected loads, we recommend to carry out the electrical wiring according to the indications given in these
Operating Instructions. lf necessary, use filters suitable for specific applications and for the type of disturbances
detected.
I)lf probes are to be used in contact with foodstuffs, make sure that the employed type of probe is in compliance
with the local sanitary / health regulations.
J)DTI products do not provide any type of protection for the connected loads against: short-circuits, overcurrent
or overvoltage, excessive temperature etc., that must therefore be protected by suitable means (such as fuses,
thermo-magnetic circuit breakers, thermal protections,etc.). At any rate the electrical power lines that (directly or
through a transformer) supply an DTI product and any other device connected to it, must be manufactured in
compliance with theregulations in force.
K)When incorporating an DTI product in other devices, where any malfunction whatsoever of the DTI product
could cause a form of risk to persons, animals or things, it is ABSOLUTELY MANDATORY to provide a suitable
safety device, other than the DTI product, that automatically starts operating in case of a failure.
L)DTI products cannot be used as critical components in life supportdevices or systems without an expressly
written approval of the Managing Director of DTI.
2 GENERAL DESCRIPTION

DCLDD1x0xx
Loading cycle of a boiler with one level probe:
The loading function regulates and controls the correct level of water in the boiler.
If the level probe in not covered by water, then the pump and solenoid valveoutput are simultaneously activated. When the
probe is reached by water, the pump and solenoidvalveoutputare deactivated and remain switched off until the status of the
probechanges again.

6 MAINTENANCE
6.1 Cleaning
Clean the front panel of the instrument with a soft cloth, dampened with soapy water. We recommend to not use
abrasive detergents or detergents that contain solvents, since they could damage the instrument; also, do not splash
water or any other liquid directly on the instrument.
6.2 Repairs
All repairs must be carried out by authorized personnel. Opening the instrument container or tampering with the
controller automatically annuls the warranty. lf necessary, consult the nearest DTI customer assistance.
7 CALIBRATION
All controllers are automatically computer calibrated at the DTI production facilities. lf the indicated temperature
value is not correct, check the connections, as well as the probe cables, especially when different cables are connected
to each other. lf it is not possible to eliminate the failure, then set the value to be added or subtracted in parameter
#19, in order to reach a correct indication of the process variable.
8 ABOUT THE OPERATING INSTRUCTIONS
These operating instructions are to be considered part of our product and are therefore to be kept with proper care
until the product itself is disposed of. The user can directly request new operating instructions from DTI, should those
supplied have been damaged or lost. These operating instructions include the technical state-of-the-art at the
moment the product was sold and, as such, cannot be considered inadequate only because they were successively up-
dated on the basis of new experiences. DTI reserves itself the right to modify product features and/or to up-date the
operating instructions at any time, without giving prior notice and without the obligation to up-date previously issued
versions. The user can request possible up-dates or integrations directly from DTI; he/she may also request further
information about the product and in turn make proposals on how to improve these operating instructions. The
information included in these operating instructions shall serve to illustrate the use of the product as foreseen in the
project, to list its technical features,
to supply information about instrument installation and regulation, to prescribe maintenance procedures, to list
residual risks, etc. Hence DTI assumes no responsibility deriving from the improper use of its products or use by
incompetent personnel, incorrect installation, faulty power supply, serious lack of prescribed maintenance, non-
authorized modifications or interventions, the use of spare parts that are either not original or not specific for this
series of models, not fully complying with the operating instructions, force majeure, etc.
