This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.

Hardware Bus Termination
The bus termination can be realised enabling the slide switch on board (120 Ohm resistor). Factory
setting disabled (see „Fig. 2 Design and components“, Digital version J3).
Address setting via Software
All DIP switches at position 0 → address has to be set via Software (via EE-
PCS Product Configuration Software or via protocol BACnet / Modbus).
Default address 44.
Example: Slave address is set via configuration software.
Address setting via Dip-Switch
Setting the DIP switches to any other address than 0, overrules the default

5 Installation
• Mount the EE610 onto a vertical, smooth surface.
• Important: The pressure connection nipples must point downwards.
• Avoid installation close to heaters and sources of strong electromagnetic interference.
• Insert the cable for supply voltage and output signal through the cable gland and connect it to the
spring terminals according to the wiring diagram („Fig. 3 Connection diagram“).
• Important: Make sure that the connecting cable or wires do not impact with the push buttons in order
to prevent unintentional trigger of the span or zero point adjustment.
• Close tightly the cable gland. This is essential for the compliance with the IP65 / NEMA4 protection
class of the EE610 enclosure.

• Install first the pressure connection nipples (included in the scope of supply) onto the duct.
Use a Ø 7.5 mm drill.
• Connect the pressure hose (included in the scope of supply) first to the EE610 and then to the nipples
at the duct. Route the pressure hose for avoiding sharp bends which might lead to the hose
obstruction („Fig. 9 Pressure hose route“).
Fig. 9 Pressure hose route
Important: Make sure to connect the higher pressure at the “+” pressure connector and the lower
pressure at the “-“ pressure connector. Inverted connection leads to “out of range” information on the
optional display and at the analogue outputs, see „4.1.6 Outputs“ and „7.2.3 Out of range“.
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.
12
User Manual EE610 Low Differential Pressure Sensor
Page 13
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).
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.
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 5 Pa for the 0 – 100 Pa range. In such a case, the zero point
adjustment can be forced by pressing and holding the zero point button for min. 10 sec.
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 positive measurement range.
Example:
Analogue version: (see „4.1.1 Select the measurement range with S1 and S2“, Tab. 1)
EE610-HV51A7, S1 = 0, S2 = 1, span value = +25 Pa
Digital version: EE610-HV51J3, span value = +100 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 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 sec.
g. The successful span point adjustment is confirmed by the green LED turning on for 2 seconds.
