Only for model T2 (duct mounting). Drill the hole for inserting the probe into the duct wall,Fig. 7 on page 11. The relevant position of top left mounting screw of the back cover with respect to the probe center: Metal enclosure: x = 28.5 mm (1.1") y = 37.5 mm (1.5") Polycarbonate enclosure: x = 20.5 mm (0.8") y = 25.4 mm (1") 2. Fix the back cover of EE23 onto the wall / panel using 4 screws (diameter max. 4.2 mm (0.2") ; not included in the scope of supply). The device shall be mounted with the cable glands pointing downwards or horizontal. 3. Wire the terminals inside the back cover according to ,,Fig. 10 Connection diagram" on Page 12. 4. Insert the middle (active) part into the back cover. By this the connection pins of the middle part will plug into the terminals of the back cover and thus realize the electrical connection. 5. Place the front cover onto the middle part and close tight the enclosure using the four screws included in the scope of supply. Drilling for round holes: Drilling for long holes: Fig. 5 Mounting of metal enclosure 116 (4.5") 50.8 (2") Fig. 6 Mounting of polycarbonat enclosure 10 Operating manual EE23 humidity / temperature sensor For the wall mount model the probe must point downwards. For the duct mount model the probe must point either horizontally or downwards. Ø12 (0.5") X Ø14 (0.6") Y (0.5Ø1"1)3 Ø12 (0.5") Fig. 7 T1 Wall mount T2 Duct mount Mounting onto DIN rails EE23 with polycarbonate enclosure can be mounted also on DIN rails with the bracket HA010203 (not included in the scope of supply, see "spare parts / accessories"). 4.2 Mounting the Sensing Probe Whenever possible place the entire probe inside the space to be monitored. In case of mounting the probe into a partition wall, it is of paramount importance for accurate measurement to avoid T gradients along the probe. In case of large T difference between the two sides of the wall, it is highly recommended to insert the probe completely (up to the cable outlet) into the wall. Should this not be possible, place a thermal isolation layer on the part of the probe outside the wall (on the cable side). For probe mounting into a partition wall use the mounting flanges HA010201 for probe diameter 12 mm and HA010208 for probe diameter 5 mm. Neither the mounting flanges nor the EE23 probes are pressure rated and as such they are not appropriate for pressure tight mounting. For pressure tight requirements please see www.epluse.com for appropriate products such as EE310.

This protects the probe and the sensing head against water dripping along the cable. · For horizontal mounted probe, a drip water point should be made just before the probe. 13 (0.51") stainless steel mounting flange drip water loop Fig. 9 horizontal Mounting the sensing probe 4.3 Electrical Connection Poouwtpeurtsaunpdpslyuapnpdlyoutputs drip water protection 34 (1.3") 85 (3.3") hanging onto the probe cable alAarlamrmouotuptuptut Relais status for RH < threshold Power supply Fig. 10 Connection diagram 4.4 Connection Versions standard option E4 option AM3 1) Two M16x1.5 cable glands (one of them mounted onto the enclosure) 2) Power supply + analogue outputs: cable connector, 5-poles, straight M12 (Lumberg RKC 5/7) 3) Analogue output: cable connector, 5-poles, straight M12 (Lumberg RKC 5/7) 4) AC power supply: cable connector, 3-poles, straight (7/8-16UN) 12 Operating manual EE23 humidity / temperature sensor Pin assignment for option E4 (with supply 8...35 V DC / 12...30 V AC) plug for supply and analogue output (front view) 43 1 52 Description: V+ GND GND OUT1 OUT2 Pins: 5 4 3 2 1 Pin assignment for option AM3 (integrated supply unit for 100...240 VAC) plug for analogue outputs (front view) 43 1 52 Description: GND OUT1 OUT1 Pins: 3 2 1 plug for 100-240 V metal enclosure (front view) Description: grounding (PE) phase (L1) neutral wire (N) Pins: 1 2 3 plug for 100-240 V polycarbonate enclosure (front view) Description: phase (L1) neutral wire (N) Pins: 1 3 External diameter of supply cable: 10-12 mm (0.39-0.47") Maximum wire cross section for connecting cable: 1.5 mm² (AWG 16) The protection of the supply cable against excess current and short-circuit must be designated to a wire cross section of 0.8 mm² (AWG 18) (6A fuse). The back cover and the middle part of the metal enclosure must be grounded during operation! Operating manual EE23 humidity / temperature sensor 13 5 Calibration / Adjustment 5.1 Definitions Calibration The calibration documents the accuracy of a measurement device. The device under test (specimen) is compared with the reference and the deviations are documented in a calibration certificate. During the calibration, the specimen is not changed or improved in any way. Adjustment The adjustment improves the measurement accuracy of a device. The specimen is compared with the reference and brought in line with it. An adjustment can be followed by a calibration which documents the accuracy of the adjusted specimen. For general calibration / adjustment guidelines and for the choice of humidity reference devices please see "Calibration Instructions" at www.epluse.com/ee23 The 2-point adjustment is recommended for best accuracy over a wide RH and / or T range. Always start the 2-point adjustment with the lower adjustment point RH_low / T_low, followed by the higher adjustment point RH_high / T_high. The span between the two adjustment points must be: |RH_high RH_low| > 30 % RH |T_high T_low| > 30 °C (54 °F) The 1-point adjustment should be used only when the RH and/or T range of interest is rather narrow. The RH resp. T adjustment point should be ideally in the middle of the range of interest. Example: In a climate controlled environment with 40 % < RH < 60 % and 15 °C < T < 25 °C (59 °F < T < 77 °F), 1-point adjustment shall be performed at 50 % RH and 20 °C (68 °F). 1-point adjustment leads to very good accuracy within the range of main interest at the cost of the accuracy beyond this range. 5.2 Adjustment of EE23 Model T1, T2, T4 and T6 via Push Buttons on the Electronics Board 5.2.1 2-Point RH Adjustment Procedure / T Adjustment Procedure 1.

Press BUTTON S1 (up) and S2 (down) to adjust the measured value in steps of 0.1 % / 0.1 degC up or down to match the reference value. The change is indicated on the display (if available) or can be measured at the analogue output. 9. Press BUTTON S1 for min. 3 seconds to store adjusted value and end the first point adjustment. or Press BUTTON S2 for min. 3 seconds to exit adjustment procedure without storing the adjusted value. In both cases the LED ,,D1" and the symbol ,,CAL>" on the LC display are deactivated. 5.2.2 1-Point RH Adjustment Procedure / T Adjustment Procedure 1. For a RH humidity adjustment set the jumper to CALRH / for a temperature adjustment set the jumper to CALT. 2. Allow for the probe to stabilize at the desired RH / T for min. 30 minutes. 3. For adjustment point > 50 % RH / in the upper half of the T output scale): press BUTTONS1 for min. 3 seconds to start the procedure. The LED ,,D1" illuminates and ,,CAL<" appears on the LC display. or For adjustment point < 50 % RH / in the lower half of the T output scale): press BUTTONS2 for min. 3 seconds to start the procedure. The LED ,,D1" illuminates and ,,CAL>" appears on the LC display. 4. Press BUTTONS1 (up) and S2 (down) to adjust the measured value in steps of 0.1 % / 0.1 °C up or down to match the reference value. The change is indicated on the display (if available) or can be measured at the analogue output. 5. Press BUTTONS1 for min. 3 seconds to store adjusted value and end the first point adjustment. or Press BUTTONS2 for min. 3 seconds to exit adjustment procedure without storing the adjusted value. In both cases the LED ,,D1" and the symbol ,,CAL" on the LC display are deactivated. 5.2.3 Return to Factory Calibration To return to RH or T factory calibration set first the jumper to RH or to T respectively. During normal measuring mode (i.e. not during the adjustment procedure. LED D1 shall be off, the display shall not show "CAL") pressing BUTTONS1 and S2 together for min 5 seconds. The return to factory calibration is confirmed by a short flash of the LED ,,D1".
