INTRODUCTION
The CR3 Series Cleanroom Monitor was developed specically
to allow for monitoring of conned spaces with accuracy and
reliability.
The CR3B features remote mounted sensors for monitoring
temperature, humidity and pressure in an adjacent space from
where the main panel is mounted in. The CR3B is available with
output signal of either Analog, BACnet ® or Modbus. Standard
features include adjustable alarm relays for each parameter,
audible/visual alarms, and large LED displays.
The CR3B main panel and remote sensor module are housed in
ush tting stainless-steel plates that enables the user to wipe
down the units when necessary.

WIRING
• Deactivate the 24 Vac/dc power supply until all connections are made to the device to prevent
electrical shock or equipment damage.
• Follow proper electrostatic discharge (ESD) handling procedures when installing the device or
equipment damage may occur.
• Use 22 AWG wiring for all connections and do not locate the device wires in the same conduit with
wiring used to supply inductive loads such as motors.
• Make all connections in accordance with national and local codes.
Connect the 24 Vac/dc power supply to the terminals labeled PWR +(power) and - (common) as shown
in Figure 10. This device has a half-wave type power supply so use caution when wiring multiple
devices so that the circuit ground point is the same on all devices and the controller.
Use caution if 24 Vac power is used and one side of the transformer is earth-grounded. In general,
the transformer should NOT be connected to earth ground when using devices with RS-485 network
connections. The device is reverse voltage protected and will not operate if connected backwards.
Figure 11 shows network connections. For end of Line (EOL) device place termination resister jumper in
ON position, for all other devices, place jumper in OFF position.

ALARM RELAYS
The device has three alarm relay outputs. The outputs are Normally Open and will close when an alarm
event occurs. The alarm outputs are assigned to TEMP, RH and DP.
Each alarm can be set to operate as a low alarm, a high alarm, both low and high alarms or be disabled.
For example:
The TEMP Alarm output can be congured as a high alarm by setting TEMP Alarm Operation to High
Alarm. In this case the alarm condition will be set when the temperature exceeds the TEMP Alarm High
Setpoint. Note that alarm hysteresis and alarm on delay will also come into play, described below.
The RH Alarm output can be congured as both low and high alarms by setting RH Alarm Operation to
Both. In this case the alarm condition will be set when the RH goes above the RH Alarm High Setpoint or
below the RH Alarm Low Setpoint.
If any ALARM OPERATION is set to Disable, then that alarm will have no function and the setpoints will
be hidden on the menu.
Each alarm has a hysteresis value and an on delay time associated with it. For high alarms, the alarm
condition is set when the input value exceeds the high setpoint and it is reset when the input value
goes below the setpoint – hysteresis value. For example, if the TEMP ALARM HIGH SETPOINT = 25.0 °C
and TEMP ALARM HYSTERESIS = 0.5 °C, then the alarm condition will set at 25.0 °C and reset at 24.5 °C.
The hysteresis is opposite for TEMP ALARM LOW SETPOINT. The alarm condition will set when the input
value falls below TEMP ALARM LOW SETPOINT and will reset when the input goes above TEMP ALARM
LOW SETPOINT + HYSTERESIS.
Each alarm also has a congurable on delay. When an alarm condition is set a timer is started and the
actual alarm will not get set until the ALARM ON DELAY time has expired. If the alarm condition gets
reset before the time expires, then no alarm is generated.
All three alarm relays operate as self-resetting and non-latching. The input signal must return to non-
alarm condition before the alarm relay returns to the NO state.
ALARM SETPOINTS
Each process variable (TEMP, RH and DP) has both a high and low alarm setpoint. If the alarms are
enabled and the setpoint is not locked, then the user can change the setpoint values within a range.
ALARM LEDS
The TEMP, RH and DP each have a low and high alarm condition. When any alarm condition is set the
corresponding front panel LED will ash. The alarm LEDs mimic the alarm relays. If any alarm is disabled,
then the LED will be disabled also.
BUZZER ALARM
The buzzer alarm can be assigned to any of the TEMP, RH or DP alarms specically, or it can be assigned
to all of them. It can be disabled via BUZZER ASSIGNMENT.
If assigned, the buzzer will activate whenever the associated alarm(s) are triggered.
The buzzer reset can be congured as either manual only or automatic reset with BUZZER RESET.
In manual mode the buzzer can only be silenced by:
• removing the alarm condition or
• by pressing the front panel <SILENCE> key
In automatic reset mode the buzzer can be silenced by:
• removing the alarm condition or
• by pressing the front panel <SILENCE> key or
• automatically when the BUZZER AUTO RESET TIME expires
The buzzer is reset or silenced as described above but the alarm condition will continue to be set, this
function only silences the buzzer. If the alarm condition is reset and then set again, the buzzer will
activate again. The buzzer provides a“beeping”or “chirping”sound, not a continuous tone.

DIGITAL INPUT
The digital input signal allows detection of a dry-contact type input change. This input could be connected
to a door switch, remote nurse station silence switch, occupancy sensor etc.
The actual program function of the DI can be set with DIGITAL INPUT FUNCTION. The input may be
disabled to have no internal program function, or it may be used as a remote alarm silence with the same
function as the front panel <SILENCE> key, or it may be used as a door freeze function.
The door freeze function can be used to prevent alarms and fast ramps of the analog output when a door
is opened. In this mode, if a digital input from a door switch is detected, then the operation of the device
freezes. This means that no alarms will be generated and the analog outputs are held at the last value
before the door open occurred. The device will sit in this state until the door closes again. There is a small
delay of 10 seconds to allow the room to stabilize again after the door is closed.
MIN MAX VALUES
The program maintains the minimum and maximum value of each sensor value. The values may be
displayed via the User Menu and may also be reset via the User Menu.
MISCELLANEOUS
The displays (and associated alarm LEDs) for each process variable may be turned o if necessary using the
Installer Menu items such as TEMP DISPLAY.
Display brightness may be changed from high to low using DISPLAY BRIGHTNESS via the User Menu.
