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:

5.4.1 Application Settings
This chapter gives some details concerning the possible applications and their inputs.
Beside differential pressure measurement (Pa, kPa, mbar, mm H2O, inch WC), the EE600 can be set
up for the following applications:
Volume flow rate measurement (k-factor input)
Air velocity measurement (k-factor input)
Filter monitoring
Level indication
Volume flow measurement
By entering a k-factor under application settings, the EE600 is able to calculate the volume flow (q)
according to the formula:
q = volume flow [m3/h]
∆p = differential pressure [Pa]
k = k-factor
The k-factor is a characteristic theoretical parameter for each fan model, specified by the manufacturer
in the datasheet of the fan.
Please note: If the data sheet of the fan manufacturer specifies a different method or unit of calculating
the volume flow, the k-factor must be converted accordingly to fit the above formula.
Example: If the k-factor (kspecific) in the data sheet of the fan manufacturer applies for volume flow
calculation in m³/s it has to be converted as follows:
The calculated volume flow (q) is available via BACnet or Modbus protocol in four different units: m3/h,
m3/s, ft3/min, l/s.
The default air density (ρ20) value at standard conditions is defined as follows:
Air density (ρ20): 1,204 kg/m3@: T = 20 °C (68 °F), p = 1 013 mbar (14,7 psi)
If the air density deviates from standard conditions, a compensation for the calculated volume flow is
necessary.
By entering the specific air density (ρ´) [kg/m3] at the operating point, the EE600 applies a
compensation to the calculated volume flow (q´) according to the formula:
q'= volume flow at specific density [m3/h]
∆p = differential pressure [Pa]
k = k-factor
ρ' = specific air density [kg/m3]
ρ20 = air density at 20 °C (68 °F) [kg/m3]
Air velocity measurement
By entering a k-factor and the dimensions of the duct (round or square), the EE600 is able to calculate
the air velocity (v) out of the volume flow (q) and the area of the duct.
v = air velocity [m/s]
q = volume flow [m3/h]
A = Area [m2]
Details for k-factor see application settings for volume flow measurement.
The calculated air velocity (v) is available via BACnet or Modbus protocol in two different units: m/s and
ft/min.
Details for setting air density (when deviating from default air density at standard conditions) see
application settings for volume flow measurement.
Filter monitoring
By entering filter limits for differential pressure, the EE600 is able to calculate a contamination level for
the observed filter in order to plan for maintenance purposes.

18 User Manual EE600 Differential Pressure Sensor
For the given application setting (∆p change filter = 800 Pa, ∆p new filter = 100 Pa) a measured
differential pressure at the filter of ∆p = 450 Pa, would mean a contamination level of 50 %:
The filter contamination level is available via BACnet or Modbus protocol expressed in percentage [%].
Level indicator
By entering the density [kg/m3] of a fluid the EE600 can act as a level indicator. The differential pressure
level measurement uses the pressure values and the specific weight of the fluid to represent the level in
a tank (see Fig. 10 Mounting examples).
h = Level (cm)
∆p = Differential pressure (Pa)
ρ = Density of fluid (kg/m3)
g = Gravitational acceleration (9,81 m/s2)
By applying the positive pressure connection into the tank, the user can measure the height of the
column of that fluid.
The level measurement is available via BACnet or Modbus protocol in two different units: cm and inch.
The maximum measurable level is limited by the highest differential pressure range 0…10 000 Pa.
For example, for water with density 998 kg/m3, at 10 000 Pa the maximum height is 102 cm (40 inch).
6 Maintenance and Service
EE600 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 EE600
A periodical readjustment of EE600 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 EE600 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).
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 EE600. 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. This is 50 Pa for the 0 – 1 000 Pa range and 500 Pa from the 0 -

19
User Manual EE600 Differential Pressure Sensor
10 000 Pa range. 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 EE600 and set it according to
the EE600 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, Tab. 1)
EE600-HV53A7, S1 = 0, S2 = 1, span value = 5 000 Pa
Digital version: EE600-HV52J3, span value = 1 000 Pa
EE600-HV53J3, span value = 10 000 Pa
Observe the operation manual of the reference device.
c. Press the span point adjustment button (see 3 Product Description).
d. The successful span point adjustment is confirmed by the green LED turning on for 2 seconds.
e. The red LED turning on for 2 seconds indicate that the span point adjustment did not succeed. In
this case repeat b.
f. 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 50 Pa for the 0 – 1 000 Pa range and 500 Pa from the 0 – 10 000 Pa range. In this case, the
set point adjustment can be forced by pressing and holding the span point button for 10 sec.
g. 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 interval 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 (Auto-zero
Version Only)) 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.
