While holding the unit in place, push the panel latch over the rear of the unit
so that the tabs of the panel latch engage in the slots on the case. The panel latch
should be engaged in the farthest forward slot possible. To achieve a proper seal,
tighten the latch screws evenly until the unit is snug in the panel (Torque to
approximately 7 in-lbs [79N-cm]). Do not over-tighten the screws.

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.

INPUT RANGE JUMPER

This jumper is used to select the proper input range. The input range selected
in programming must match the jumper setting. Select a range that is high
enough to accommodate the maximum signal input to avoid overloads.

To access the jumpers, remove the meter base from the case by firmly
squeezing and pulling back on the side rear finger tabs. This should lower the
latch below the case slot (which is located just in front of the finger tabs). It is
recommended to release the latch on one side, then start on the other side latch.

Warning: Exposed line voltage exists on the circuit boards.

Remove all power to the meter and load circuits before accessing
inside of the meter.

EMC INSTALLATION GUIDELINES

Although Red Lion Controls Products are 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 a unit may be different
for various installations. Cable length, routing, and shield termination are very
important and can mean the difference between a successful or troublesome
installation. Listed are some EMI guidelines for a successful installation in an
industrial environment.

1. A unit should be mounted in a metal enclosure, which is properly connected

to protective earth.

2. Use shielded cables for all Signal and Control inputs. The shield 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 to earth ground (protective earth) at one end where the

unit is mounted.

b. Connect the shield to earth ground at both ends of the cable, usually when

the noise source frequency is over 1 MHz.

3. 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 through 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. Also, 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. Long cable runs are more susceptible to EMI pickup than short cable runs.

5. In extremely high EMI environments, the use of external EMI suppression

devices such as Ferrite Suppression Cores for signal and control cables is

effective. The following EMI suppression devices (or equivalent) are

recommended:

Fair-Rite part number 0443167251 (RLC part number FCOR0000)
Line Filters for input power cables:

Schaffner # FN2010-1/07 (Red Lion Controls # LFIL0000)

6. To protect relay contacts that control inductive loads and to minimize radiated

and conducted noise (EMI), some type of contact protection network is

normally installed across the load, the contacts or both. The most effective
location is across the load.
a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide

varistor (MOV) across an AC inductive load is very effective at reducing
EMI and increasing relay contact life.

b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor

switch, care must be taken not to exceed the breakdown voltage of the
transistor when the load is switched. One of the most effective ways is to
place a diode across the inductive load. Most RLC products with solid state
outputs have internal zener diode protection. However external diode
protection at the load is always a good design practice to limit EMI.
Although the use of a snubber or varistor could be used.
RLC part numbers: Snubber: SNUB0000
Varistor: ILS11500 or ILS23000

7. Care should be taken when connecting input and output devices to the
instrument. When a separate input and output common is provided, they
should not be mixed. Therefore a sensor common should NOT be connected
to an output common. This would cause EMI on the sensitive input common,
which could affect the instrument’s operation.

relate to Red Lion Controls products.

WIRING OVERVIEW

Electrical connections are made via screw-clamp terminals located on the

back of the meter. All conductors should conform to the meter’s voltage and
current ratings. All cabling should conform to appropriate standards of good
installation, local codes and regulations. It is recommended that the power
supplied to the meter (DC or AC) be protected by a fuse or circuit breaker.

When wiring the meter, compare the numbers embossed on the back of the

meter case against those shown in wiring drawings for proper wire position. Strip
the wire, leaving approximately 0.3" (7.5 mm) bare lead exposed (stranded wires
should be tinned with solder.) Insert the lead under the correct screw-clamp
terminal and tighten until the wire is secure. (Pull wire to verify tightness.)

CAUTION: Analog common is NOT isolated from user input common. In order to preserve the safety of the meter

application, the Analog and DC power common must be suitably isolated from hazardous live earth referenced voltage; or
input common must be at protective earth ground potential. If not, hazardous voltage may be present at the User Input and
Input Common terminals. Appropriate considerations must then be given to the potential of the input common with respect
to earth ground. Always connect the analog signal common to terminal 7.

PROGRAMMING MODE ENTRY (PAR BUTTON)

It is recommended all programming changes be made off line, or before
installation. The meter normally operates in the Display Mode. No parameters
can be programmed in this mode. The Programming Mode is entered by
pressing the PAR button. If it is not accessible, then it is locked by either a
security code or a hardware lock.

MODULE ENTRY (SEL & PAR BUTTONS)

The Programming Menu is organized into four modules. These modules group
together parameters that are related in function. The display will alternate between

 and the present module. The SEL button is used to select the desired module.

The displayed module is entered by pressing the PAR button.

MODULE MENU (PAR BUTTON)

Each module has a separate module menu (which is shown at the start of each
module discussion). The PAR button is pressed to advance to a particular
parameter to be changed, without changing the programming of preceding
parameters. After completing a module, the display will return to  .
Programming may continue by accessing additional modules.

SELECTION / VALUE ENTRY

For each parameter, the display alternates between the present parameter and
the selections/value for that parameter. The SEL and RST buttons are used to
move through the selections/values for that parameter. Pressing the PAR button,
stores and activates the displayed selection/value. This also advances the meter to
the next parameter.

For numeric values, the value is displayed with one digit flashing (initially
the right most digit). Pressing the RST button increments the digit by one or the
user can hold the RST button and the digit will automatically scroll. The SEL
button will select the next digit to the left. Pressing the PAR button will enter the
value and move to the next parameter.

return the meter to the Display Mode. (If power loss occurs before returning to
the Display Mode, verify recent parameter changes.)

PROGRAMMING TIPS

It is recommended to start with Module 1 and proceed through each module in
sequence. When programming is complete, it is recommended to record the
parameter programming and lock out parameter programming with the user input
or programming security code.

FACTORY SETTINGS

Factory Settings may be completely restored in Module 2. This is useful
when encountering programming problems.

OFSEt



The display can be corrected with an offset value. This can be used to
compensate for signal variations or sensor errors. This value is automatically
updated after a Zero Display to show how far the display is offset. A value of
zero will remove the effects of offset. The decimal point follows the dECPt
selection.

FILtr



If the displayed value is difficult to read due to small process variations or
noise, increased levels of filtering will help to stabilize the display. Software
filtering effectively combines a fraction of the current input reading with a
fraction of the previous displayed reading to generate the new display.

Filter values represent no filtering (0), up to heavy filtering (3). A value of 1
for the filter uses 1/4 of the new input and 3/4 of the previous display to generate
the new display. A filter value of 2 uses 1/8 new and 7/8 previous. A filter value
of 3 uses 1/16 new and 15/16 previous.

bANd



The filter will adapt to variations in the input signal. When the variation
exceeds the input filter band value, the filter disengages. When the variation
becomes less than the band value, the filter engages again. This allows for a
stable readout, but permits the display to settle rapidly after a large process
change. The value of the band is in display units, independent of the Display
Decimal Point position. A band setting of ‘0’ keeps the filter permanently
engaged at the filter level selected above.

General Notes on Scaling

1. When using the Apply (APLY) scaling style, input values for scaling points

must be confined to the range limits shown.

2. The same Input Value should not correspond to more than one Display Value.
(Example: 20 mA can not equal 0 and 20.)

balanced hysteresis is used. For alarm applications, usually unbalanced
hysteresis is used. For unbalanced hysteresis modes, the hysteresis functions on
the low side for high acting setpoints and functions on the high side for low
acting setpoints.

Note: Hysteresis eliminates output chatter at the switch point, while time delay

can be used to prevent false triggering during process transient events.

Figures. The “on” output may be manually reset (off) immediately by the
front panel RST button or user input.The output remains off until the trigger
point is crossed again.

LAtCH = Latch with immediate reset action; This action latches the output on at

the trigger point per the Setpoint Action shown in Setpoint Output Figures.
Latch means that the output can only be turned off by the front panel RST
button or user input manual reset, or meter power cycle. When the user input
or RST button is activated (momentary action), the corresponding “on” output
is reset immediately and remains off until the trigger point is crossed again.
(Previously latched alarms will be off if power up Display Value is lower than
setpoint value.)

L-dLY = Latch with delay reset action; This action latches the output on at the

trigger point per the Setpoint Action shown in Setpoint Output Figures. Latch
means that the output can only be turned off by the front panel RST button or
user input manual reset, or meter power cycle. When the user input or RST
button is activated (momentary action), the meter delays the event until the
corresponding “on” output crosses the trigger off point. (Previously latched
outputs are off if power up Display Value is lower than setpoint value. During
a power cycle, the meter erases a previous L-dLY reset if it is not activated at
power up.)
