LAE electronic LTR15 Instructions For Installation And Use

INSTRUCTIONS FOR INSTALLATION AND USE.
LTR15
Thank you for having chosen a LAE electronic product. Before installing the instrument, please read these instructions carefully to
ensure maximum performance and safety.

1. INSTALLATION

1.1. LTR15 is sized 77x35x77 mm (WxHxD). It is inserted into the panel through a hole 71x29 mm and secured by pressing
gently into the relative clamps. The rubber gasket should be placed between the instrument frame and the panel, checking its seal
to avoid infiltration.
1.2. The instrument should operate at an ambient temperature between -10°...+50°C and relative humidity between
15%...80%. To reduce the effects of electromagnetic disturbance, ensure that the sensor and signal cables are well separated from
the power conductors.
1.3. The supply voltage, switched powers and arrangement of connections must be in compliance with the indications given
on the container.
CAUTION: if the relays must frequently change over a heavy load, it is advisable to contact the manufacturer to obtain indications
regarding the lifetime of the contacts.
Whenever products are to be stored within very rigid specifications or they are very valuable, it is advisable to use a second instrument
that can activate or warn in the event of any malfunction.

2. CONTROL PARAMETERS

The regulator is adapted to the controlled system by suitably programming its configuration parameters from the setup menu. The
instrument comes with a general setup and cannot therefore be used without having first checked that the parameters are correct.
Setup is accessed by pressing in succession the keys
available parameters appear in TABLE 1 shown below.
Use the button to pass from one parameter to the next, to pass to the previous one press button
value press the key , to change it press
touched for 30 seconds, exit is automatic.
The set point 1SP may also be displayed and adjusted during normal regulator operation by pressing the key
set point in any case remains within the limits SPL and SPH.
