When the lock test limit switch level is reached, the status field changes into BL block. The default setting is on interface 1 I1.

CA Calibrate With this command the displacer is pulled up until it is halted against the tank top reference. The drum and drum should now move towards you with a axial movement of minimum 1 mm and maximum 2.

This is the lowest allowed position for the displacer during normal operation. HCU board to interface optional equipment as: Low level alarm set point. This information can be displayed on the internal display, the Portable Enraf Terminal PET as well as on remote systems. The ATG covers can optionally be provided with sealing facilities on blocking devices, which prevents unauthorized opening.

UN Unlock Give an unlock command to cancel the calibrate command. This manual describes the commissioning, maintenance and trouble shooting of the basic Manuql level measurement. Solve the problem; clean the displacer. For verification of the level calibration, refer to section 4. Close the drum compartment cover.

Check the availability of ample room to suspend and move the test weights about 60 cm downwards should be sufficient. It is recommended to read this description mnual to performing any of the procedures.


Disconnect the mains and transmission cabling from the back-plane! Disconnect the infra-red connector from the back-plane. Do not kink the measuring wire and handle drum carefully.

The transmission address identifies the gauge on the Honeywell Enraf 2-wire field bus. The following procedure will do. The voltage selector is located inside electronic compartment on the top of backplane.

Check motor and reference encoder excessive oil? For protection type increased safe EEx e approved glands are to be used.

Safety Page 10 2. This results in a stable and accurate averaged level measurement. If that is not correct, enter the engraved drum circumference. The ullage value is also transmitted to the host via the 2-wire Honeywell Enraf field bus or optional RS-channel. For a complete overview, refer to Item documentation for Honeywell Enraf series ATG and in the item help of the service tool Engauge.

Mankal dip mode is cancelled when one of the interface measurements is selected. Connect the shield of the cable externally in the cable gland at both ends of the cable. EX Exit protection level. Maintenance Instruction manual ATG Page 37 Clean the displacer when the displacers weight differs more then 3 g from the value in item DW, or recalibrate the force transducer with the test weights refer to section 5.

Then the gauge goes into block mode BL. The value you enter now, is overwritten when the level calibration with displacer stop is used. CD can be set between 01 minimum contrast and 16 maximum contrast.

CA Calibrate Neraf displacer will now raise from the ball valve. Remove the displacer from the measuring wire.

Attg the flat cable connecting the motor block to the back-plane. Switch L allows scrolling through several additional displays. It is coupled to the ATG via an infra-red coupling. Program frequency 1, measured with test weight of g.

Enter the position of the top of the ball valve with respect to the tank zero adding the immersion depth of the displacer at the product level. Locate the transport bracket see figure 3. The power rating of the external resistor depends on the value of the resistor. It is recommended to read this description prior to performing any of the procedures. The transmission address identifies the gauge on the Honeywell Enraf 2-wire field bus.

Open the drum cover.

Then the gauge goes into block mode BL. That can be calculated manal follows refer to figure 3. Exit protection level 4.

When the XPU detects an error about a certain item, that item follows the error code, separated by a space. The floating point format is a fixed format; Standard floating point format: Give correct setting in item F0, or calibrate force transducer refer to section 5.

If implemented and maintained correctly, the safety parameters for the Documents. S1 Set point Standard floating point format; units:
