3、 Installation method:

If it is in an open environment, the bracket installation method is generally used, and the instrument is fixed with its own flange or nut, with standard thread for the instrumentG2Can match various specifications of flanges（PPFlanges, carbon steel flanges, stainless steel flanges, to be matched according to actual on-site needs. If the pool or tank is cut slightly larger than the probe diameter at the installation position（60mm）Insert the instrument into the circular hole and tighten the flange or nut from bottom to top. Installation must ensure that the probe surface of the instrument is level with the measured liquid level

The wiring of the instrument depends on whether the selected instrument is a two-wire or four wire system. By referring to the instruction manual, the wiring can be quickly connected. If the range needs to be changed, follow the operating steps to make the changes

4、 Instrument debugging (see operating manual for details):

Liquid level calibration:After the instrument is installed and powered on, the liquid level value will be displayed on the LCD, but this data often does not match the actual liquid level, so liquid level calibration is required. as long asP04Once the menu is set, the liquid level calibration will be automatically performed(Liquid level valueH)And distance calibration(spacing valueL).

Press when the instrument is working normallySETEnter the parameter settings menu with the key, press the ▲ key to selectP02The menu, the second line of numbers is20mACorresponding liquid level, pressOKSet the key.

Probe installation height setting and automatic liquid level calibration(P04)

P04The menu is for setting the installation height of the probe, which must be a true and valid value. After setting the effective installation height value, it will be automatically calibratedHandLvalue(namely:Liquid level value and spatial distance).

Reaction speed setting（P05）

P05The menu can change the instrument response speed. The faster the liquid level changes, the faster the corresponding instrument response speed is required. This instrument has4Medium mode available for selection:00 The fastest response speed;01 Faster response speed;02 Medium speed response speed;03 Slow response speed.

Press the ▲ key to select the desired mode and then pressOKConfirm with the key.

[Attention]The faster the response speed of the instrument, the greater the fluctuation of the displayed data; On the contrary, the slower the response speed of the instrument, the more stable the displayed data. If the liquid level does not change very quickly, there is generally no need to modify the factory settings.

IDNumber setting（P07）(Note: Only the four wire system has this function!)

When used for communication, especially for multi machine communication, the default is01.

Relay output setting (note: only four wire system has this function!)

The instrument is equipped with two relays, namelyH(upper limit)，L(lower limit). PressSETKey, password interface appears:“0000”Press the [▲] key to change one digit of di to3, press【OK】Press the key to enter the relay parameter setting menu interface.

Each set of relays has two parameters corresponding to it, namely the control value and the hysteresis value.H(upper limit)Relay is determined by menu parametersH(Control value) anddH(Return difference value) control;L(lower limit)Relay is determined by menu parametersL(Control value) anddL(Return difference value) control.

For high point relays（H）When the measured value changes from small to large and exceeds the control value（H）When the relay is closed; When the measured value is less than the difference between the control value and the return value（H-dH）The relay is disconnected.

For low point relays（L）When the measured value changes from large to small and is less than the control value（L）When the relay is closed; When the measured value is greater than the control value plus the difference value（L+dL）The relay is disconnected.

Relay (alarm type)

pressSETThe password interface appears on the key“0000”Press the [▲] key to change one digit of di to4, namely:“4000”, press【OK】The key can enter the relay settings,PH:01For high-level alarm,PL：02For low-level alarms, set the alarm type according to the requirements (for example, if two high-level alarms need to be set as)PH:01ThePL:01Low level alarm is set toPH:02ThePL:02This function can be achieved.
