LAE electronic LTS12 - User Manual

To Next Page

We thank you for choosing an LAE electronic product. Before proceeding to the installation of this unit, please read this

instructions sheet carefully; only in this way you will obtain maximum performances and safety.

1. INSTALLATION

1.1 LTS12 has got a size of 77x35x77 mm (WxHxD), it must be inserted into the panel through a 71x29 mm hole and

secured via the suitable brackets exerting correct strength. The rubber gasket must be placed between the panel and the

instrument front, so please make sure that there are no gaps allowing liquid infiltrations.

1.2 The unit works with an ambient temperature between -10°.. +50°C and 15%.. 80% relative humidity. To reduce the

effects of electro-magnetic interference, place the probe cable and the unit itself as away as possible from power lines.

1.3 Probe and power supply must be connected strictly following the diagram appearing on the enclosure. If present, the

probe screen must be earthed, by connecting it to the metal frame. If needed, the unit must be powered by means of the

suitable transformer mod. TRxxx.

Where delicate or valuable products have to be maintained under strict conditions, please use a separate controller for limit

and alarm functions.

2. CONFIGURATION (SETUP)

Thanks to the configuration parameters, the LTS12 can suit scale, resolution and sensor type. Access to the configuration

takes place through the following sequence: switch off the unit, keep buttons + pressed, then switch on unit again. Scroll

through the parameter list with or until you get to the desired one, then get its value displayed with and change it

with + or .

Exit from the SETUP takes place by letting the keypad untouched for 10 seconds.

Parameter SCL provides the readout scale, i.e.: with SCL=01 there is no modification of the measured value, while with

SCL=02, there is a scale conversion from °C to °F (to be used for temperature measurements only). In this latter case, 0.1

resolution is not available.

With SCL=01 resolution is based upon the value set to ACC; with ACC=01 or 02 resolution is set to respectively 1 or 0.1.

With ACC=03 you will obtain the maximum resolution allowed by the display, i.e.: 0.1 for values between –19.9 and 99.9

and 1 outside of these limits.

Through SIM it’s possible to simulate different sensor response times to changes of the value measured, therefore: by setting

SIM to values greater than 0, the resulting effect will be a proportional reduction of the displayed data change.

If the model you own accepts two types of input, then select the one you want to use by means of parameter TYP following

the table here below:

SCL Readout scale 01=normal, 02=°F

ACC Resolution 01=1; 02=0.1; 03=autorange

TYP Type of sensor 0; 1

LOR Minimum range limit -199 .. 999

HOR Maximum range limit -199 .. 999

SIM Display indication slowdown 0 .. 100
