1INTRODUCTION
HD 0CR-AS is a relative r differential l w pressure transmitter and data l gger de-
signed f r wall flush-m unting. Measuring range ±100 Pa.
A silic n piez resistive sens r with high accuracy and temperature c mpensati n is
used, which all ws excellent linearity, repeatability and stability ver the time. The
aut -zer ing feature all ws stable measurements ver the time with ut the need t
recalibrate.
An input f r an pti nal relative humidity and temperature c mbined pr be is pr vid-
ed. The abs lute humidity, the Dew P int and the wet bulb temperature can be calcu-
lated.
Three 0…5/10 V and 0/4…20 mA anal g utputs and a digital RS485 utput with
“Slave” Modbus-RTU pr t c l f r c nnecting the instrument t a netw rk f sens rs
are available.
The electr luminescent display has an inattinic red pr tecti n. The fr nt keyb ard al-
l ws scr lling the real time measurements and c nfiguring the instrument.
Equipped with a USB p rt with mini-USB c nnect r f r the c nnecti n t a PC.
F r each detected quantity, tw alarm thresh lds can be set by the user. Exceeding a
thresh ld is signaled ac ustically, by means f the internal buzzer, and visually, by
lighting the alarm LEDs n the fr nt panel ( nly f r the three measurements ass ciat-
ed with the anal g utputs). An alarm hysteresis and a delay in the generati n f the
alarm can be c nfigured f r each detected quantity.
The PC s ftware HD3 AP-S all ws c nfiguring the instrument, viewing the real time
measurements, d wnl ading and viewing the data int a database. The HD3 AP-
CFR21 s ftware pti n all ws the pr tecti n f rec rded data and c nfigurati n in re-
sp nse t FDA 21 CFR part 11 rec mmendati ns.
Brushed stainless steel fr nt panel.
The instrument is supplied fact ry calibrated.

3.1 CONFIGURATION
The perating parameters f the instrument can be c nfigured in vari us way:
•Via fr nt keyb ard (see chapter 7).
•Via the HD35AP-S applicati n s ftware, c nnecting the instrument t the PC via
USB.
•Via the M dbus-RTU pr t c l and the RS485 c nnecti n (see chapter 8).
The HD35AP-S applicati n s ftware is d wnl adable fr m Delta OHM website F r the
use f the applicati n s ftware, see the c rresp nding instructi ns.

4ALARMS
F r each detected quantity, tw alarm thresh lds can be set by the user. The alarm is
generated if the measured value falls bel w the l wer thresh ld r rises ab ve the up-
per thresh ld.
Exceeding a thresh ld is signaled:
•ac ustically, by means f the internal buzzer (if enabled);
•visually, by lighting the alarm LEDs n the fr nt panel ( nly f r the three meas-
urements ass ciated with the anal g utputs);
An alarm hysteresis and a delay in the generati n f the alarm can be c nfigured f r
each detected quantity.
The amplitude f the hysteresis is in percentage (0...100%) f the difference between the
tw alarm thresh lds. F r example, if the hysteresis is 2% (default value), the l wer
thresh ld is 10 °C and the upper thresh ld is 60 °C, the hysteresis in °C is equal t (60-
10)x2/100= 1 °C.
60 °C
59 °C
11 °C
10 °C
The alarm is generated after the set delay time r immediately if the “no delay” pti n
is selected (default). If the alarm c nditi n disappears bef re the delay time has
elapsed, the alarm is n t generated.

59 °C

Enabling the Buzzer Latch pti n, the buzzer c ntinues t s und even after the alarm
c nditi n has ceased.
In the event f an alarm in pr gress with the buzzer active, the buzzer can be silenced
f r a c nfigurable time. Once the set time has elapsed, the buzzer will resume s unding

STATISTICAL FUNCTIONS
The instrument calculates and displays the maximum (MAX), minimum (MIN) and
average (AVG) value f the detected measurements.
In rder t display the statistical inf rmati n, press FUNC/: the instrument sh ws
the maximum value f the displayed quantity. T scr ll the maximum values f the
vari us quantities use the key.
By pressing FUNC/ again, the instrument sh ws the minimum value f the dis-
played quantity. By pressing FUNC/ again, the instrument sh ws the average value
f the displayed quantity.
By pressing FUNC/ nce m re, the instrument asks if the calculati n f the statisti-
cal values is t be reset (FUNC CLR). Select YES r nO using / keys, then c nfirm
with the MENU/↵ key.

HD50CR-AS - 11 - V1.1
6CALIBRATION
The instrument calibrates aut matically at regular intervals (default 60 minutes, the in-
terval is c nfigurable) the zer f the differential pressure, temp rarily disc nnecting
the pressure inputs thr ugh an internal s len id valve.
Via the Fb00 menu (see chapter 7) it is p ssible t perf rm a manual calibrati n in ne
r tw p ints. In rder t perf rm manual calibrati n, it is necessary t unscrew the
tw fr nt caps that c ver the calibrati n inputs. T perf rm zer calibrati n (Fb05 in
the menu), leave b th inputs pen. T perf rm calibrati n at n n-zer values (gain
calibrati n, Fb08 in the menu), c nnect the fr nt inputs t a l w differential pressure
generat r.
The differential pressure zer calibrati n is als p ssible via the M dbus C il register
with address 72 (see chapter 8).
At the end f the calibrati n r verificati n, firmly screw the fr nt caps s that the seal
is tight and the inputs are n t affected by the external pressure.
Via the Fb00 menu it is als p ssible t calibrate the relative humidity sens r f the
c mbined temperature and relative humidity pr be at p ints 33% RH and 75% RH.
Warning: the pti nal c mbined relative humidity and temperature pr be must be
calibrated in line with the instrument. If the pr be is rdered with the instrument, the
pr be is already fact ry calibrated. If the pr be is rdered later, the calibrati n must
be perf rmed by the user via the Fb00 menu.

7MENU
The menu accessible via the fr nt keyb ard all ws displaying the instrument inf r-
mati n and changing perating parameters. The menu is structured in levels, with
main categ ries and submenus.
T access the menu, y u need t enter the user password (c nfigurable thr ugh the
appr priate menu item) r the administrator password (supplied with the instru-
ment and n t editable). Entering the user passw rd makes s me settings n t change-
able.
The instrument exits aut matically the menu if n key is pressed f r 3 minutes. After
exiting the menu, the passw rd remains active f r a few minutes, during which y u
may enter the menu again with ut re-entering the passw rd. It is p ssible t exit the
menu by disabling immediately the passw rd by perf rming a passw rd level reset in
the Password menu.
T access a menu parameter, pr ceed as f ll ws:
1. Press MENU, the first digit f the passw rd will blink.
2. Using / keys, set the first digit and c nfirm (MENU/↵ key), the sec nd digit f
the passw rd will blink. Set the remaining digits in the same way.
3. Using / keys, select a main categ ry in the menu and c nfirm (MENU/↵ key).
4. If the selected main categ ry has a submenu, select the desired item using /
keys and c nfirm (MENU/↵ key).
. Using / keys, select the desired parameter: the parameter current setting is
displayed.
6. T change the selected parameter, if all wed, press MENU/↵, the parameter set-
ting blinks. Use / keys t change the setting, then c nfirm (MENU/↵ key).
Y u can fast f rward by keeping r key depressed.
T exit the main menu r a sub menu, press ESC key.
If it is n t all wed t change a parameter, the n tice N/A (N t Available) will appear
when trying t change it.
