Signet 8900 Multi-Parameter 3
2. Description
The 8900 Multi-Parameter Controller takes the concept of modularity to the extreme. Two base units, one with back-lit LCD and the other with vacuum fl uorescent display can be confi gured by the user in the fi eld.
Ultimate fl exibility is achieved via plug-in modules for two, four or six input channels, universal AC line voltage or 12 to 24 VDC power, up to four analog outputs, and up to four relays. The controller will support up to four additional relays, for a total of eight, by way of external relay modules.
Absolute input versatility allows mixing and matching of up to six sensors with digital (S
3
L) output. Up to two of the possible six input channels may be used for Signet fl ow sensors with frequency output. The 8058 Signal Converter module enables any 4-20 mA signal to be used as input to the 8900.
2.1 Compatibility
Model numbers of sensors and external relays compatible with the 8900 are identifi ed in the tables below.
• For two channel systems, mix and match up to two of any of these sensors.
• For four channel systems, mix and match up to four sensors with S 3 L output.
• For Six channel systems, mix and match up to six sensors with S
3
L output.
• The optional external relays connect via S
3
L to the I/O Module, but do NOT consume a sensor input channel.
• pH and conductivity sensors include temperature sensors. These "secondary" measurements are treated by the 8900 as separate sensors with respect to display, output and relay functionality, but they do NOT consume separate input channels.

3. Installation and Basic Functionality
This section lists all items included with individual 8900 system components, describes installation detail for plug-in modules and base units, and provides information and instruction on the basic functionality of the plug-in modules.
3.1 Unpacking
Base units, plug-in modules, accessories and spare parts are sold, packaged and shipped separately from the factory. Unpack all components carefully. The following items accompany every 8900 base unit:
• 8900 Base Unit (back-lit LCD or Vacuum Fluorescent display)
• Front Face Panel Gasket (pre-installed on base unit)
• Quick-clip panel mounting bracket
• Instruction Manual, Paper copy – English
• CD-ROM containing instruction manuals in English, French, German, Spanish, Italian and Portuguese
For future reference, for each installation, it is recommended to record the part number and serial number of each of the components listed here:
Facility Tag Number or System ID (user assigned):_______________________

Output Module 3-8900.405-____ S/N___________________
Comm Module 3-8900.404-____ S/N___________________
3.2 Tools and Equipment Required:
• Philips screwdriver (medium tip)
• Standard screwdriver (small/medium tip)
• ¼-DIN punch or jigsaw suitable for cutting panel opening to within 1 mm (0.020 in.) tolerance.
• If the 8900 Base Unit will be mounted in a panel, plug-in modules may be installed either before or after the base unit is mounted.
If the 8900 Base Unit will be mounted using the accessory Wall Mount Bracket, fi rst install plug-in modules.
• Plug-in modules are packaged in anti-static bags and contain individual instruction sheets and removable terminals for convenient wiring. Minimize handling of plug-in modules to reduce the probability of damage due to static discharge.
• Power Modules include adhesive labels to be applied to the outside of the 8900 enclosure in specifi c locations as illustrated in
section 4.2.
• The rear panel of the 8900 must be removed prior to installing or removing plug-in modules. If plug-in modules are already installed, the terminals must be removed prior to removing the rear panel. It may be helpful to use a standard screwdriver to gently pry removable terminals away from the receptacle on the plug-in modules.
• Use a Philips screwdriver to loosen the two captive screws at the bottom of the panel. Pinch one of the screws and swing the panel up approximately 90°, using the tab hinge at the top of the panel, and pull it straight away from the base unit. Reverse this step to reinstall the panel after the plug-in modules are installed.

• Up to two sets of two relays may be installed directly into the 8900. The modules are completely independent of one another, so it is not necessary for Relays 1 & 2 to be installed in order to use Relays 3 & 4.
• However, in accordance with the labeling on the rear panel, relays installed directly into the 8900 via these plug-in modules will always be identifi ed in the 8900 menus as
Relays 1 & 2 and 3 & 4, respectively.
• The red LED relay status indicators on the front panel of the 8900 are hardwired to
Relays 1 & 2. If the slot for Relays 1 & 2 is vacant, the red LEDs will be inoperative.
Status of all relays is available at all times in a single screen in View mode.
• It is perfectly acceptable to mix and match the relay types installed directly in the 8900, as well as between internal and external modules.
• Any and all relays are freely assignable to any channel. Hysteresis and time delay are adjustable for each relay.
Power Connection
• Dry-contact relays are electromechanical switches with a moving contact armature. They are suitable for many general-purpose applications, AC or DC, including AC loads up to 250 V.
• Solid-state relays are electronic switches with no moving parts. They may be used with AC or DC loads, but have lower current handling capability and voltage ratings than Dry-contact relays. Solid-state relays will outlast Dry-contact relays in pulsing applications.
• Switching active loads (most commonly inductive) can cause contact arcing suffi cient to damage both types of relays. The RC Filter Kit or
"snubber" is available as an accessory to reduce or eliminate these damaging effects.

• The 8900 will support up to eight (8) relays, though only four actually fi t directly inside its compact
1
/

DIN enclosure. 8059 External Relay Modules of either two or four relays may be connected to the 8900 via S 3 L at the I/O Module (this does
NOT consume a sensor input channel).
• External relays are completely independent of internal relays, so it is not necessary for Relays 1 & 2 or 3 & 4 to be installed in order to use the external relays. In the 8900 menus, external relays will always be identifi ed as Relays A,
B, C and D.
• 8059 versions with power supply are powered by universal AC line voltage and may be used to power the 8900 with 24 VDC. Also, S
3
L pass-thru terminals on the 8059 can help to reduce sensor wiring congestion at the 8900. See the
8059 instruction manual for details.
• External Relays mount on DIN rail inside a panel and can be tested remotely from the 8900, or locally with switches built-in for convenience. They also include LED relay status indicators, but the status of these and all relays is available at all times in a single screen in the 8900 View mode.
• Any and all relays are freely assignable to any channel. Hysteresis and time delay are adjustable for each relay.
• It is perfectly acceptable to mix and match relay types between internal and external modules. However, NOTE: The 8900 only allows external relays to be used in modes Off, Low, Hi, Window, USP and Advanced.
• 8059 External Relay Modules contain dry-contact relays only. These electromechanical switches are suitable for many general-purpose applications,
AC or DC, including AC loads up to 250 V.
• Switching active loads (most commonly inductive) can cause contact arcing suffi cient to damage relays. The RC Filter Kit or “snubber” is available as an accessory to reduce or eliminate these damaging effects.

6. Wiring
All wiring connections to the 8900 are made via the removable terminals of the plug-in modules. This section contains instructions and diagrams for wiring each type of module. Several helpful tables, explanations and recommendations are also provided. In general:
• Do not allow any AC leads that may be connected to the Power Module, or to optional internal relays, to come in contact with low voltage wiring.
• Terminals accept 12 to 24 AWG wire.
• Strip 10 to 12 mm (0.4 to 0.5 in.) of insulation from wire tips and tin bare ends to eliminate fraying.
• Use ferrules when connecting more than one wire to a single terminal.
• Insert wire tip or ferrule completely into the terminal and secure with the screw.
• The I/O Module provides the terminals for sensor inputs, optional external relays, and optional Analog Outputs 1 & 2.
• These modules (3-8900.401-X) support frequency and S 3 L sensor input signal types. External relays are controlled via S 3 L and connect to the I/O Module just as if they were S
3
L sensors. External relays do NOT consume a sensor input channel.
• Refer to Section 6.4: Output Module for wiring optional Analog Outputs 1 & 2.
The maximum allowable cable length for fl ow sensors with frequency output is dependent upon the output signal strength of the sensors themselves, and the degree to which the signals are susceptible to EMI or "noise". This is largely a function of whether the sensors are self-powered, or powered by an external source.
All of the sensors in the table below are compatible with the 8900. The three models limited to 60 m (200 ft.) are self-powered sensors.
The 8900 automatically provides power to the others via the I/O Module (normal sensor wiring).
These maximum recommended cable lengths apply to individual sensors and are completely independent of one another. Additionally, these cable lengths have no relevance to any S 3 L devices that may also be connected to the I/O Module.

(S

L) Input wiring
• The maximum cable length of the digital (S 3 L) bus varies depending on the types of sensors connected and the size of the conductors in the cable. For best results, determine the maximum cable length for the system before routing cables.
• Frequency input signals from fl ow sensors are not part of the digital bus, so they do not impact the cabling calculations. Follow the maximum cable specifi cations published in the fl ow sensor literature.
• The L bus can be connected to two sets of terminals on the 8900. Divide S
3
L sensors between the two points to stay within the limits defi ned here.
• There are several methods that can help route the digital cables and remain within the distance limitations. The following pages provide general wiring concepts for different systems.
* 2551 Magmeter and the 8900
The 2551 Magmeter may require up to 15 mA per unit under some conditions. Special attention must be paid to power requirements when more than three 2551 Magmeters are connected to the 8900.
To ensure that Magmeters receive suffi cient power, Signet recommends minimizing other power requirements in the 8900 by doing at least ONE of the following: • Select solid state relay cards instead of dry contact relays.
• Select Passive analog output cards instead of Active.
• Select the DC power supply card instead of the AC card.
Any one of these measures will insure that the 8900 has suffi cient power available to support up to six 2551 Magmeters.
How to Wire S
3
L Sensors
1. Tie all red wires together.
2. Tie all white wires together.
3. Tie all black wires together.
4. Tie cable shield to white GND wire at one end only for added protection from noise interference.
Notes:
• Some installations may require connecting the cable shield to Earth ground to overcome noise interference.
• Terminals 4-7 may be used as Freq Input 2 or as S 3 L Input 2, but not both.
• For best EMI fi ltering, divide digital sensors between S
3
L Input 1 and S
3
L Input 2 if Input 2 is not required for Frequency input.
• Daisy-chain or multi-drop wiring for S
3
L devices will reduce the number of separate digital signal lines that must be connected to the 8900 I/O Module.
• Ferrules are recommended when connecting multiple S 3 L devices to a single set of terminals.
• In a "Daisy-Chain" pattern, the wires from each sensor are spliced to the matching wire of the adjacent sensor.
• In a "Multi-Drop" pattern, the wires from each sensor are spliced to a common set of wires from the 8900.
• Wiring methods can be mixed in any convenient design when connecting S
3
L devices. See the wiring charts on the following pages for a variety of wiring options.
• The specifi c type of sensors on a branch of the S
3
L bus determine the current requirements, and the maximum cable length for the branch. See section 6.2.1 for details.

** The digital (S 3 L) communication link between the 8900 and the 8059 is powered by the 8900 and consumes 1 mA maximum.
However, the 8059 External Relay Module always requires a separate power source for its operation.
Step 2 Determine the Maximum length of each branch of the S
3
L Bus
This chart determines the maximum length of one branch of the S3L bus. This distance is important because it ensures that the digital signal can successfully travel the length of the cable and still be detected by the 8900.
• Find the column nearest to the total current in this branch, as determined in step 1.
• Find the cable gauge or wire dimensions that most accurately represent the cable being used.
• The number at the intersection of these factors represents the maximum cable for one branch of the S
3
L bus.
• The top section references AWG cables, the lower section is based on METRIC cables.
• Dividing the sensors between two branches will greatly increase the maximum cable length of each branch.
Example: 40 mA total on one branch can sustain 70 ft of cable. 20 mA on two branches can sustain 140 ft. on each branch.

Signet 8900 Multi-Parameter
All of the basic system setup functions are automated in the 8900, with the exception of Channel Type assignments. These must be done by the user. After Channel types are assigned, the 8900 will automatically complete all of the remaining tasks in the System
Setup menu. This includes assigning each sensor connected to the 8900 to a matching channel, and confi guring one display for each channel. After installation and wiring is completed, follow the steps below.
NOTE: Automatic Sensor Recognition occurs each time the 8900 is powered on. See the following page for additional information.
8.1 System Setup: Channel Type
Example: Set Channel 1 to operate as a Flow Channel:
1. Start from View Mode (normal operation). In a new unit, the View display depends on the type of I/O module.
2. Hold the ENTER key for 2 seconds. When the display shows "Menu Directory-System Setup", release, then press ENTER again.
3. Press the RIGHT key, then enter the password. (Factory standard setting is UP-UP-UP-DOWN, Enhanced is 0-0-0-0)
4. The channel type will be fl ashing "None". Press the DOWN key three times to scroll to "Flow".
5. Press the ENTER key to select Flow. The display will show two warning messages, then ask "Are You Sure?"
Press the RIGHT key to change the fl ashing response to "Yes", then press the ENTER key to fi nalize the change.
6. The display will show "Saving" for a few seconds, then return to the root menu.
Press the DOWN key to scroll to the next channel type setting, then repeat steps 4 and 5.
7. If all settings in this menu are complete, press the UP and DOWN keys together again to return to the Menu Directory.
8. Press the UP and DOWN keys together once more to return to the View mode and normal operation.
The display will now show the information from the sensor assigned to Channel 1.

6 Sensor(s) and
1 Ext Relay(s)
After a channel type is assigned (section 8.1), the 8900 compares the sensor identifi cation list with each channel type and assigns a sensor to each channel, following a specifi c heirarchy:
1. All Channels: Native sensors (sensors of the same measurement type as the channel type) will be assigned fi rst.
If multiple sensors of the same type are listed, the lowest serial number will be assigned fi rst.
Frequency inputs are considered the native type for fl ow channels.
2. All Channels: 4-20 mA sensors (from 8058 Signal Converter) will be assigned only if no native sensors are listed.
If no compatible sensors are listed for a channel, or if all compatible sensors are already assigned, then no automatic channel assignment will be made.
Channels: 3 L type fl ow sensor will be assigned only if no frequency input is detected.
Level Channels: If no level sensors are listed, a pressure sensor will be assigned to the level channel.
Manual override option: Use the "Channel ID" function to reassign sensors.
• The Channel ID menu will only list sensors that match the channel type being assigned.
• Removing a sensor from the wiring bus does NOT erase a channel assignment. The display will show "CHK SENSOR" for that channel until a sensor is manually reassigned.
• A new display will be automatically confi gured for each channel (only where one of the six confi gurable displays has both lines set to "None".)
• Conductivity, Level and pH channels are allotted two-line displays to view both primary and secondary measurements. All other channel types are assigned a single-line display.
• Standard displays for each channel type are illustrated below.
Manual override option: Confi gurable VIEW displays can be modifi ed with the "Screen--Line--" functions in System Setup menu.

Pulse Width Modulation
• PWM automatically varies the ratio of ON time to OFF time proportional to minimum and maximum range settings.
• The relay period is the sum of the time a relay is ON and the time it is OFF.
• Relay pulse width is the time the relay is ON.
• The 8900 must be programmed with the relay period, and with the low and high setpoints.
• The 8900 does not allow use of this mode for Pressure applications.
Example:
• The pulse width will be 0% of the relay period (relay always OFF) when the process value is less than the minimum range.
• The pulse width will be 100% of the relay period (relay always
ON) when the process value is greater than the maximum range.
• The pulse width will be 60% of the relay period when the process value is at 60% of the span between the minimum and maximum range.

Volumetric Pulse
• A pulse is generated each time a specifi ed volume of fl uid is registered. For fl ow inputs only.
Totalizer Volume
• Relay activates and latches when a specifi ed volume of fl uid is registered. For fl ow inputs only.
• Total Volume mode counts the TOTALIZER Units until the setpoint volume is reached, then activates the relay until the resettable totalizer is reset.
• If the Resettable Totalizer reading is greater than the setpoint, the relay will be activated immediately. The relay will be relaxed when the totalizer is reset to zero.
• This mode is useful to trigger a reminder when a process is due, as for a backwash cycle or fi lter change.
Advanced
• Relay is activated when a set of three conditions (a, b and c) are met. See detailed explanation in Section 11.2.

11.2 Multiple Relay Sources and Advanced Relay Mode
When a Relay Source is set to "MULTIPLE" and the Relay Mode is set to "Advanced", the relay can be activated by up to three different conditions. ADVANCED mode presents four Boolean logic formulae called "Relay Operators." Each Operator can be programmed with up to three different conditions. The relay will only be activated when the complete formula is satisfi ed.
• A TRUE condition means that the parameter is beyond the setpoint.
• A FALSE condition means that the parameter is within the setpoint.
• If any one of the three conditions shows "CHK SENSOR" then that condition will be treated as always FALSE.
Boolean Relay Logic Operations
(a l b l c) means
"Activate this relay when either a OR b OR c is true."
Relay 1 Operator
( a | b | c ) >
(a l (b & c) ) means
"Activate this relay if a is true
OR if b AND c are both true."
Relay 1 Operator:
( a |(b & c) ) >
Relay 1 Operator:
( a & b & c ) >
(a & b & c) means
"Activate this relay only when a AND b AND c are all true."
Relay 1 Operator:
( a &(b | c) ) >
(a & (b l c) ) means
"Activate this relay only if a is true
AND either b or c are also true."
Program a Relay for Advanced Operation
Example: Set Relay #1 to activate IF pH3 falls below 5, OR if pH4 rises above 8.5, OR if Level L6 rises above 18 inches. Relay #1 will activate 30 seconds after any one the conditions are met.
Condition a:
Condition b:
Condition c:
The pH on Channel 3 is less than 5.
The pH on Channel 4 is greater than 8.5
The Level on Channel 6 is greater than 18.
When operating properly, all three of these conditions are FALSE. If any one of them becomes TRUE, then Relay 1 will be activated.
Relay 1 will remain activated until the TRUE condition becomes FALSE again, including the hysteresis band.

Appendix A: Derived Functions
When two or more measurements of the same type are present, the 8900 can calculate several derived functions from like pairs.
Up to three derived Functions can be defi ned and used as the source for display and output functions.
• Flow, Temperature, Pressure, and Level channels must have matching units. (fl ow channels must also have same timebase)
• Conductivity channels will automatically scale to µS/cm before the function calculation is made.
•
Three derived measurements can be applied to any set of sensors, regardless of type.
• Ratio:
• Difference:
• Sum:
Measurement 1 ÷ Measurement 2
Measurement 1 - Measurement 2
Measurement 1 + Measurement 2
% Passage and % Reject
• % Passage and % Reject are derived from conductivity measurements only, specifi cally for use in reverse osmosis systems.
• % Passage is the amount of contaminates remaining in the product water compared to the level of contaminates in the feed water. For example, if the feed water measures 100 µS and the product water measures 5 µS, the % Passage is
(5 ÷ 100) x 100, or 5%.
• % Reject is the amount of contaminates rejected to the concentrate water compared to the amount of contaminates in the feed water. For example, if the % Passage is 5%, the
% Reject is 95%.
• Decreasing Reject values and increasing Passage values usually indicate a problem with the RO membrane.

Permeate
Feed
% Passage: (Permeate ÷ Feed) x 100
% Reject: [1 - (Permeate ÷ Feed)] x 100

% Recovery
• % Recovery is a derived measurement based on fl ow rate only. In a reverse osmosis system, % Recovery is fl ow rate in the permeate (product) compared to the fl ow rate of the incoming feed water.
• To measure % Recovery, the 8900 must have two fl ow sensors connected. They may be located in the Feed line, the Concentrate line or the Permeate line.
• The 8900 provides 3 different methods for calculating
Recovery to accomodate any confi guration.
• Both fl ow sensors must use the same timebase and units of measure.

Appendix C: Conductivity/Resistivity Application
Temperature Effects
Conductivity measurement is highly dependent on temperature.
The basic rule is that higher temperatures result in greater conductance (less resistance).
Temperature effects are expressed as the percentage of conductivity change (in µS) per °C. The conductivity value is generally referenced to 25 ºC. The 8900 has three temperature compensation options:
None
USP standards for pharmaceutical waters require that the measurement be made without temperature compensation. USP limits are discussed in Appendix D.
Pure Water (Standard Compensation)
This selection is used for measurements of very clean water, less than 0.2 µS. Temperature effects are not linear in this range, so the temperature coeffi cient is not easily determined.
This selection is recommended for all Resistivity applications measuring from 5 MΩ to 18 MΩ. This selection conforms to
ASTM standard D1125 and D5391.
Linear
This selection allows you to calculate a custom temperature compensation value for Conductivity measurements in the range of 0.2 µS and greater (Resistivity applications measuring less than 5 MΩ). The procedure is outlined in the section on the right.
Calculating a Linear Temperature Coeffi cient
1. Set TC Mode to NONE (see SETUP menu).
2. Heat a sample solution close to the maximum process temperature. Place sensor in the sample solution and allow several minutes for stabilization. Record the 8900 temperature and conductivity values in the spaces provided:
Displayed temperature:
Displayed conductivity:
T1 = _______ °C
C1 = _______ µS
3. Cool the sample solution close to the minimum process temperature. Place sensor in the sample solution allowing several minutes for stabilization. Record displayed temperature and conductivity values in the spaces provided:
Displayed temperature:
Displayed conductivity:
T2 = _______ °C
C2 = _______ µS
(A 10% change in conductivity between steps 2 and 3 is recommended.)
4. Substitute recorded readings (steps 2 and 3) into the following
formula:
TC Slope = 100 x (C1 - C2)
(C2 x (T1 - 25)) - (C1 x (T2 - 25))
TDS Factor
Some industries need to display a conductivity value as Total
Dissolved Solids (TDS), measured in units of parts per million
(PPM) or parts per billion (PPB).
• 1 PPM is equivalent to 1 mg per liter.
• 1 PPB is equivalent to 1 µg per liter.
• The 8900 calculates PPM or PPB by dividing the µS value by a TDS Factor that you defi ne.
• TDS factors can vary widely, ranging from 1.50 to 2.50 µS per PPM. Methods for establishing a TDS factor are beyond the scope of this manual.
• The 8900 will accept TDS factor values from 0.01 to 99999.9
µS per PPM.
(factory preset = 2.00 µS per PPM)
Example: A sample solution has a conductivity of 205 µS @
48°C. After cooling the solution, the conductivity was measured at 150 µS @ 23°C. (C1 = 205, T1 = 48, C2 = 150, T2 = 23)
The TC is calculated as follows:
TC Slope = 100 x (205 - 150) = 5500 = 1.42%/°C
(150 x (48 - 25)) - (205 x (23 - 25)) 3860
Conductivity Calibration Procedure
NOTE: The 8900 TDS factor must be set in PPM.
TDS Factor = Conductivity (µS) ÷Total dissolved solids (PPM)
PPM = Solution conductivity (µS) ÷ TDS Factor
Example:
• Solution conductivity = 150 µS
• TDS = 80 PPM
• TDS Factor = 150 µS ÷ 80 PPM = 1.88 µS per PPM
Wet Calibration with NIST Traceable Solutions:
• When using NIST traceable standards, review the temperature information provided with the test solution.
• Prevent contamination of the test solution.
• The sensor must be at the temperature specifi ed on the test solution label.
• Remove the sensor from the system and rinse in a small amount of test solution.
• Place the sensor into the test solution. Gently stir/shake the electrode to dislodge any air bubbles on the electrode.
• Place a reference thermometer into the same solution.
• Allow suffi cient time for the temperature to stabilize.
• Set Temp: Adjust the temperature value based on the reference thermometer.
• Set Cond: Adjust the conductivity value based on the test solution value.
• Verify the linearity of the 8900 by placing the sensor into a second test solution of a different value.
• If the 8900 does not display the correct value (Temperature ±
0.5 ºC, Conductivity ± 2% of reading), service is required.
Signet 8900 Multi-Parameter 43
Appendix D: USP Limits
USP (United States Pharmacopoeia) has defi ned a set of conductivity values
(limits) to be used for pharmaceutical water. The standard requires that conductivity measurement without temperature compensation be used for these applications.
The limits vary according to the temperature of the sample. The 8900 has the USP limits stored in memory. It will automatically determine the proper USP limit based on the measured temperature.
Using the USP function
USP setpoints are defi ned as a percentage below the USP limit, so a USP alarm is always a HIGH alarm. The 8900 can be set to warn you if the conductivity approaches within a set percentage of the USP limit.
The following settings and conditions are required for a USP relay function:
1. In the Setup menu:
• RELAY MODE must be set to USP.
• RELAY SOURCE must be a Conductivity channel
• SOURCE UNITS must be set to µS.
2. In the OPTIONS menu:
• The TC Mode of the USP channel must be set to None.
(If a relay is constantly on when it should be off, check relay settings listed above.)
Example:
• The USP setpoint is 40%.
• The water temperature is 19 ºC, so the USP limit is 1.0 µS.
• The relay will be activated when the conductivity value reaches 0.6 µS, or 40% below the 1.0 USP limit.
• If the water temperature drifts to more than 20ºC, the 8900 will automatically adjust the USP limit to 1.1.
• The relay will now be activated when the conductivity value reaches 40% below 1.1 µS, or 0.66 µS.
When the temperature range is:
0 to < 5ºC
5 to < 10ºC
10 to < 15ºC
15 to < 20ºC
20 to < 25ºC
25 to < 30ºC
30 to < 35ºC
35 to < 40ºC
40 to < 45ºC
50 to < 55ºC
55 to < 60ºC
60 to < 65ºC
65 to < 70ºC
70 to < 75ºC
75 to < 80ºC
80 to < 85ºC
85 to < 90ºC
90 to < 95ºC
95 to < 100ºC
100 to < 105ºC
