5.2.6 Freely Configurable Custom Modbus Map
It is possible to map measured value/status registers arbitrarily in a block with up to 20 registers
provided for this purpose. This means that registers of interest may be mapped in an area with
consecutive registers, so that important values can be queried with a single command in one block.
The custom map can be configured via:
1. PCS10 Product Configuration Software and the USB configuration adapter HA011066.
The PCS10 can be downloaded free of charge from www.epluse.com/pcs10.
2. Modbus protocol commands, refer to the example in chapter 5.6 Modbus RTU Examples.
The register block for the configuration of the customisable Modbus map consists of the registers
6001 (0x1770) to 6010 (0x1779). For the blockwise query of the measured values behind Modbus
registers 3001 (0xBB8) to 3020 (0xBCB), the firmware accesses this configuration area and thus gets
the information which measured value/status registers are to be output. A maximum of 10 user-defined
registers can be mapped. The table below shows an example:

5.2.7 Device Status Indication
If a critical error occurs, all Modbus values are set to NaN (according to IEEE754 for data type
FLOAT32) or to 0x8000 (INT16). It is possible to read out all status and error information via Modbus
register 602 (0x259). Errors are displayed in bit-coded form. If an event is present, the corresponding bit
is set to 1.
Measured values outside the measuring range are limited with the corresponding limit value.

6 Maintenance and Service
EE610 does not require any special maintenance, nevertheless it is recommended to perform a zero
point adjustment every 12 month. If needed, the enclosure may be cleaned and the device may be re-
adjusted as described below.
6.1 Cleaning
Use a damp soft cloth to remove deposits of dust or dirt from the exterior of the device and from the
display. Do not attempt to clean the interior of the device. Do not use any solvents, alcohol or abrasive
cleaning agents.
6.2 Repairs
Repairs may be carried out by the manufacturer only. The attempt of unauthorised repair excludes any
warranty claims.
6.3 Readjustment of EE610
A periodical readjustment of EE610 might be required by the regulations of certain industries or by the
need of best long-term measurement accuracy. The zero point and the span point can be adjusted with
push buttons on the EE610 electronics board.
For adjustment the device must be powered and the enclosure cover removed. Consequently, the
adjustment may be performed by authorised staff only, observing the handling of electrical sensitive
devices (ESD).

User Manual EE610 Low Differential Pressure Sensor
6.3.1 Zero Point Adjustment
The zero point adjustment is used to correct an eventual zero point deviation.
a. Remove the tubes from both pressure connections of the EE610. By this the pressure equal on
both connections. If the sensor has an auto-zero setting, the tubes do not need to be removed.
b. Press “zero point” button 1-2 sec. (see 3 Product Description).
c. The successful zero point adjustment is confirmed by the green LED turning on for 2 seconds.
d. The red LED turning on for 2 seconds indicates that the zero point adjustment did not succeed. In
this case repeat b.
e. The zero point adjustment (b.) may not succeed because of a deviation higher than 5 % of the
original full scale of the device. If the zero point adjustment is not successful even after pressing the
button for at least 10 seconds, then the deviation is too high for zeroing. Please check the sensor,
the tubes and the environment and make sure that the pressure connection nipples are free.
f. The successful zero point adjustment is confirmed by the green LED turning on for 2 seconds.
6.3.2 Span Point Adjustment
The span point adjustment is used to correct an eventual deviation of the span value.
Important:
Make sure to perform a zero point adjustment as above before any span point adjustment.
a. Connect the differential pressure reference device/calibrator to the EE610 and set it according to
the EE610 span value to be adjusted.
b. Note: The span value has to be set according to the selected measurement range.
Example:
Analogue version (see 5.1.1 Select the Measurement Range with S1 and S2):
EE610-HV51A7, S1 = 0, S2 = 1, span value = +25 Pa
Digital version: EE610-HV51J3, span value = +100 Pa
c. Observe the operation manual of the reference device.
d. Press the span point adjustment button (see 3 Product Description).
e. The successful span point adjustment is confirmed by the green LED turning on for 2 seconds.
f. The red LED turning on for 2 seconds indicate that the span point adjustment did not succeed. In
this case repeat b.
g. The span point adjustment (b.) may not succeed because of a deviation higher than 5 % of the
original full scale of the device.
This is 5 Pa for the 0 – 100 Pa range. In such a case, the set point adjustment can be forced by
pressing and holding the span point button for 10 s. If the zero point adjustment is not successful
even after pressing the key for at least 10 seconds, then the deviation is too high for zeroing. Please
check the sensor, the tubes and the environment and make sure that the pressure connection
nipples are free.
h. The successful span point adjustment is confirmed by the green LED turning on for 2 seconds.
6.3.3 Return to Factory Adjustment
a. Press and hold simultaneously both “zero” and “span” buttons for 5 sec.
b. The successful return to factory adjustment is confirmed by the green LED turning on for 2 seconds.
c. The red LED turning on for 2 seconds indicates that the return to factory adjustment
did not succeed. In this case repeat b.
Important: Return to factory adjustment affects both, zero and span.
6.3.4 Auto-zero (Optional)
With auto-zero, no maintenance of the sensor is necessary. Auto-zero is carried out every 24 hours
(factory setting). Changing the interval is possible with PCS 10 and the USB configuration adapter (see
chapter 5.4 PCS10 Product Configuration Software). The intervall can be set from 10 minutes up to 7
days. For this purpose DIP switch 9 (see chapter 5.1.6 Select the Source of Settings with S9) has to be
in position 1 (ON). During the auto-zero procedure (takes approx. 4 s), the green LED flashes quickly
(see chapter 3.4.1 LED Indication) and the most recent measured value is frozen.
