DESCRIPTION
The CUB4L offers large 0.48 inch high digits. The LCD is available in
Positive Image Reflective (CUB4L000) , Negative Image-Transmissive with yellow/green backlighting (CUB4L010) , or Negative Image-Transmissive with red backlighting (CUB4L020) .
The backlight versions require power from an external 9 to 28 VDC supply.
The optional power supply (MLPS0000) is designed to be attached directly to the rear of a CUB4L and is powered from a 115/230 VAC source. This supply will provide power for the backlighting of the unit and a sensor.
These Cubs can be mounted into the same panel cut-out as the CUB2 series of products. The CUB4L counters are manufactured using a CMOS LSI counter circuit chip, mounted on a gold-plated substrate, which is electrically connected by ultrasonic wire-bonding. Use of proven micro-electronic assembly and manufacturing techniques provides these units with the reliability and dependability required for industrial service.
The CUB4L series has a lightweight, high impact plastic case with a clear viewing window. The sealed front panel with the silicone rubber reset button meets NEMA 4X/IP65 specifications for wash-down and/or dusty environments, when properly installed.

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.
INSTALLATION ENVIRONMENT
The unit should be installed in a location that does not exceed the maximum operating temperature and provides good air circulation. Placing the unit near devices that generate excessive heat should be avoided.
The bezel should be cleaned only with a soft cloth and neutral soap product. Do NOT use solvents. Continuous exposure to direct sunlight may accelerate the aging process of the bezel.
Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to operate the keypad of the unit.
Installation
The CUB4 series of products meet NEMA 4X/IP65 requirements for indoor use, when properly installed. The units are intended to be mounted into an enclosed panel. The viewing window and reset button are factory sealed for a washdown environment. A sponge rubber gasket and mounting clip are provided for sealing the unit in the panel cut-out.
The following procedure assures proper installation:
1. Cut panel opening to specified dimensions. Remove burrs and clean around panel opening.
2. Carefully remove the center section of the panel gasket and discard.
Slide gasket over rear of the unit to the back of the bezel.
3. Assemble nut fastener first and then mounting screw onto both sides of mounting clip. Tip of screw should not project from hole in mounting clip.
4. Install CUB4 unit through the panel cut-out until front bezel flange contacts the panel-mounted gasket.
5. Slide the mounting clip over the rear of the unit until the mounting clip is against the back of the panel. The mounting clip has latching features which engage into mating features on the CUB4 housing.
Note: It is necessary to hold the unit in place when sliding mounting clip into position.
6. Alternately tighten each screw to ensure uniform gasket pressure. Visually
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:
Ferrite Suppression Cores for signal and control cables :
Fair-Rite # 0443167251 (RLC #FCOR0000)
TDK # ZCAT3035-1330A
Steward #28B2029-0A0
Line Filters for input power cables :
Schaffner # FN610-1/07 (RLC #LFIL0000)
Schaffner # FN670-1.8/07
Corcom #1VR3
Note: Reference manufacturer’s instructions when installing a line filter.
5. Long cable runs are more susceptible to EMI pickup than short cable runs.
Therefore, keep cable runs as short as possible.
inspect the front panel gasket. The gasket should be compressed about 75 to 80% of its original thickness. (Recommended torque is 28 to 36 in-oz.)
If not, gradually turn mounting screws to further compress gasket.
7. If gasket is not adequately compressed, and mounting screws can no longer be turned, loosen mounting screws and check that mounting clip is latched as close as possible to panel.
Repeat procedure for tightening mounting screws.

LOW SPEED COUNT INPUT, 50 Hz MAX. [For 250 Hz see note in text]
Pulling the “L.S. CNT.” Input to Common with a mechanical or solidstate switch increments the counter. The low pass filter (1meg resistor and
4700pf cap) used with a Schmidt trigger circuit debounces mechanical switch signals. The switch load is 14 µA (max. voltage drop 0.5 V) when
ON. The OFF-state leakage current must be less than 2 µA. Reed switches, mercury wetted contacts, snap action limit switches, and silver alloy relay
HIGH SPEED COUNT INPUT, 5 KHz MAX.
contacts with wiping action are usually satisfactory for generating count input signals. Motor starter contacts, tungsten contacts, and brush-type contacts should NOT be used.
Note: By parallel connecting both “H.S. CNT.” and “L.S. CNT.” inputs, count speed can be increased to 250 Hz if debounce is not needed.
The “H.S. CNT.” Input allows the CUB Counter to operate at speeds up to
5 KHz when driven by bi-polar outputs. Input drive voltage must be limited to 28.0 V maximum to avoid damage to the counter.

(Low) = +0.5 V max.
BACKLIGHT OPTION
Connecting a wire from the “RST. EN.” (Reset Enable) Input terminal to
Common will enable the front panel Reset button. When Remote Reset is required, a wire is connected from the “ REM. RST.” input terminal to
Common. Pulling this input low causes the counter to reset. The “REM.
RST.” can be pulled low by either a mechanical switch or solid-state transistor switch. Switch load and leakage are the same as for “ L.S. CNT.” Input above.
Note: The RC protection circuit on the “REM. RST.” Input causes a delay of approximately 15 msec in Reset response.
Optional backlight versions of the CUB4L require an external 9-28 VDC power supply. The external supply is connected between the V+ and Common terminals as shown in the drawing.
Red Lion Controls optional power supply (MLPS0000) is designed to be attached directly to the rear of a CUB4L and is powered from a 115/230 VAC source. The MLPS provides power for unit backlighting and a sensor.

WIRING CONNECTIONS
The electrical connections are made via rear screw-clamp terminals located on the back of the unit. When wiring the unit, use the label to identify the wire position with the proper function. All conductors should meet voltage and current ratings for each terminal. Also cabling should conform to appropriate standards of good installation, local codes and regulations. It is recommended that power supplied to the unit (AC or DC) be protected by a fuse or circuit breaker. Strip the wire, leaving approximately 1/4" bare wire exposed
(stranded wires should be tinned with solder) . Insert the wire into the screwclamp terminal and tighten down the screw until the wire is clamped tightly.
Each terminal can accept up to two #14 AWG wires.
Note: The CUB4L000 will NOT have a screw terminal installed at the V+ terminal, since it is NOT required for operation and is not internally connected. The CUB4LM00 uses the V+ screw terminal to mount the
MLPS power supply. It is not internally connected to the unit.
Warning: Lithium battery may explode if incinerated. Signal input voltage should not exceed 28.0 VDC to prevent damage to the counter.
