incrementing edge of input signal.
Voltage Input (CUB7P1xx): 10 V min. to 300 V max. (AC 50/60 Hz. or DC)
to Common, 150 V max. for backlight versions. 30 cps max. Input current
0.5 mA max. ANY off-state leakage current may prevent counter from
activating.
5. REMOTE RESET: 15 msec min. pulse width (active low) from 3.0 V
bipolar output, an open collector transistor, or a switch contact to common.
6. ENVIRONMENTAL CONDITIONS:
Operating Temperature Range: 0 to 50°C Derate max. operating
temperature to 40°C above 26 VDC (Backlight versions).
Storage Temperature: -30 to 80°C
Operating and Storage Humidity: 85% max. relative humidity (non-
condensing) from 0°C to 50°C.
Altitude: Up to 2000 meters
7. CERTIFICATIONS AND COMPLIANCES:
SAFETY
IEC-1010-1, EN 61010-1: Safety requirements for electrical equipment for
measurement, control, and laboratory use, Part 1.
IP65 Enclosure rating (Face only), IEC 529
Type 4X Enclosure rating (Face only), UL50
ELECTROMAGNETIC COMPATIBILITY
Notes
1. Backlit powered units require a power line filter to be installed, RLC
LFIL0000 or equivalent, so as not to impair the function of the
backlighting.
Refer to EMC Installation Guidelines for additional information.
8. CONSTRUCTION: High impact plastic case with clear viewing window.
The front panel meets NEMA 4X/IP65 requirements for indoor use when
properly installed. Installation Category I, Pollution Degree 2. Panel gasket
and mounting clip included.
9. WEIGHT: 2 oz. (57 grams) [with battery]
PROGRAMMING
The CUB7P has programmable prescale values and decimal point positions.
These values are changed using the front panel push buttons. Connect wires
between RST EN (Reset Enable) and COM. (Common); and between HS
(Program Enable) and COM. (Common) to enable front panel push buttons.
Note: Upon entering the PGM mode for the first time, the Prescaler value is
set to 0.0000. Some value between 0.0001 and 1.9999 must be entered in
order for the CUB7P to operate properly. Previously stored values are
retained until changed by the user.
With the front panel push buttons enabled, press the PGM button to enter the
program mode. The CUB7P display will change to the current prescale value,
with the least significant digit flashing at a 2 Hz rate. The prescale value can be
set to any value between 0.0001 and 1.9999. Press the RST button to increment
the flashing digit to the desired value. Pressing the PGM button will lock in the
value of the flashing digit and advance to the next significant digit. The most
significant digit can only be set to 0 or 1. When the entire prescale value has
been programmed, press the PGM button once to enable decimal point
selection. Any new count pulses will be accumulated using the new prescale
value.
After performing the prescale selection, the display will show 0.0000.
Decimal point positions can be set for:
Press the RST button until the desired decimal point position is displayed.
Press the PGM button to select that position and return to the counter mode.
Remove the wire from the HS (Program Enable) terminal to prevent accidental
changes to the programmed values.
Note: The incrementing edge of the count signal will change when the PGM
button is pressed for the first time. To avoid incorrect display information, it is
recommended that the CUB7P be reset after making programming changes.
COUNT EDGE
Accessing program mode for the first time will complement the incrementing
edge of the count signal. See below for the incrementing edge of the count
signal for the CUB7P1:
After installing or replacing battery: Falling Edge
After entering program mode: Rising Edge
EMC INSTALLATION GUIDELINES
Although this unit is designed with a high degree of immunity to
ElectroMagnetic Interference (EMI), proper installation and wiring methods
must be followed to ensure compatibility in each application. The type of the
electrical noise, source or coupling method into the unit may be different for
various installations. In extremely high EMI environments, additional measures
may be needed. The unit becomes more immune to EMI with fewer I/O
connections. Cable length, routing and shield termination are very important
and can mean the difference between a successful or a troublesome installation.
Listed below are some EMC guidelines for successful installation in an
industrial environment.
1. Use shielded (screened) cables for all Signal and Control inputs. The shield
(screen) pigtail connection should be made as short as possible. The
connection point for the shield depends somewhat upon the application.
Listed below are the recommended methods of connecting the shield, in
order of their effectiveness.
a. Connect the shield only at the panel where the unit is mounted to earth
ground (protective earth).
b. Connect the shield to earth ground at both ends of the cable, usually
when the noise source frequency is above 1 MHz.
c. Connect the shield to common of the unit and leave the other end of the
shield unconnected and insulated from earth ground.
2. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be run in metal conduit that is properly
grounded. This is especially useful in applications where cable runs are
long and portable two-way radios are used in close proximity or if the
installation is near a commercial radio transmitter.
3. Signal or Control cables within an enclosure should be routed as far away
as possible from contactors, control relays, transformers, and other noisy
components.
4. In extremely high EMI environments, the use of external EMI suppression
devices, such as ferrite suppression cores, is effective. Install them on
Signal and Control cables as close to the unit as possible. Loop the cable
through the core several times or use multiple cores on each cable for
additional protection. Install line filters on the power input cable to the unit
to suppress power line interference. Install them near the power entry point
of the enclosure. The following EMI suppression devices (or equivalent)
are recommended:
