CEB09BV Transmitter operating modes The CEB09BV Transmitter, like all the display flow meter transmitters that exist on the market, have 2 modes of operation: · MEASUREMENT MODE. It is the normal operation mode of the instrument. · CONFIGURATION MODE. It is the one used to modify the instrument's operating parameters. 4.1. Measurement mode 4.1.1. Display description The main elements of the CEB09BVtransmitter display are shown below: 1. Top line. Depending on the "Display Mode", it can indicate Instantaneous Flow or Partial Volume (or Mass). 2. Lower Line. Depending on the "Display Mode", you can indicate the Total Volume (or Mass) or the Partial Volume (or Mass). 3. This label indicates that the top line shows Instantaneous Flow. 4. This label indicates that the Lower line (and sometimes the upper line) shows the Volume (Partial or Total) of liters. If, in the configuration of the equipment, a different density than 1000 gr/liter is selected, this label disappears. 5. MODE key. This key has several uses depending on the "Display Mode" and is activated with a magnetic key that is supplied with the equipment. 6. ZERO key. If the Partial Volume is displayed on the Upper or Lower line, this key sets it to zero using the magnetic key supplied with the equipment. 7. Arrows indicating: · Instantaneous Flow Units (l / m, l / h, m3 / h, kg / m, kg / h, t / h). · If the data outputs (Pulse and Analog) are active. 8 4.1.2. Display modes CEB09BV Transmitter User Manual The CEB09BV transmitter display can show three types of data: · Instantaneous Volumetric Flow (volume per unit of time) · Partial Volume with reset · Total volume without resetting NOTE: If a liquid density other than 1,000 gr/liter is selected in the equipment configuration (see section 4.2), the CEB09BV transmitter would indicate the Flow, Partial or Total mass. These 3 values can be displayed on the 2 lines of the screen, in different ways depending on the Display Mode. The CEB09BV transmitter has 3 different Display Modes: MODE MODE 1 MODE 2 MODE 3 DISPLAY MODES TOP LINE LOWER LINE FLOW FLOW FLOW / PARTIAL PARTIAL / TOTAL PARTIAL TOTAL The user can select the "Display Mode" that best suits his needs, accessing the equipment configuration (see section 4.2). Modes 1 and 3 are typically used in fixed installations and Mode 2 in portable installations.

Configuration mode CEB09BV Transmitter User Manual Access, navigation and modification of the equipment parameters is done from outside the CEB09BV transmitter. You don't need to physically access the electronics like you did in previous versions. Access and modification of internal parameters must always be carried out by qualified personnel. Any incorrect alteration can cause the Transmitter to malfunction. 4.2.1. Access and Navigation in Configuration Mode. Modification of Parameters a. Keys and their meaning The CEB09BV transmitter has only 2 keys: 1. MODE located in the lower left part of the Transmitter and 2. ZERO located lower right To activate each of these keys, just move the magnetic key supplied with each device. However, these two keys become 4 depending on how long we keep the magnetic key on each key: MODE ZERO SHORT KEY Approach and quickly remove the magnetic key. MODE ZERO LONG KEY Approach and hold the magnetic key for 4 seconds until the message ESPERE (wait) appears. A decreasing counter is displayed on the top line until the message SUELTE (release) is displayed. 11 CEB09BV Transmitter User Manual Note: In the different diagrams of this manual these symbols are used so that the user knows at all times if he has to apply a LONG KEY (more alive symbol) or SHORT (dimmer symbol). Screens that appear when the LONG KEY is activated: When the key is held over each key, the LONG KEY is activated and the following screens appear to guide the user: · WAIT screen. At the bottom appears the word ESPERE (wait) and at the top the number 4 that decreases until it reaches zero. The magnetic key must remain next to the key since, if it is separated from the key before reaching zero, the spindle returns to the previous screen without having performed any function. · RELEASE screen. When the countdown reaches zero, the SUELTE (release) screen appears. This message tells the user that they can remove the magnetic key from the key. In this way, you will go to the next screen, which will be different depending on each situation. Note: This operation has been developed so that the user knows at all times what he is doing and has been the result of communication with our clients. 12 CEB09BV Transmitter User Manual b.
