measure between pH - Cl2 - mV - NTU.
fig. 4
Once into “measure submenu”*, is possible to edit (all or some) the following setpoint parameters:
[DxA] “setpoint output A” that can be configured as on/off, PWM or PID and settable as 1 to 6 channel
[DxB] “setpoint output B” that can be configured as on/off, PWM or PID and settable as 1 to 6 channel
[PxA] “proportional pump output A” and settable as 1 to 6 channel
[PxB] “proportional pump output B” and settable as 1 to 6 channel
[MAx] “mA output” settable as 1 to 6 channel
[AxA] “general alarm A” for “out of limits” reading parameters
[AxB] “general alarm B” for “out of limits” reading parameters
[ADx] “general alarm” for maximum dosing time
[ARx] “general alarm” for damaged probe (same reading after a set time)
Total amount of output-channels available is 6. This number decreases every time a channel is assigned to a specific
function during setup. Once there are no more channels available the instrument will read only probe’s value.
DxA and DxB.
Using DxA and / or DxB is possible to control the status of “setpoint outputs” and “level outputs” based on some
rules. Refer to “power connections” and “I/O connections” blocks at page 4 and 5 to locate these outputs on mainboard.
Once that DxA or DxB function is enabled (move wheel over “disable” , press, rotate to “enable”, press again to exit) the
main parameters are MODE (ON/OFF - PWM - PID), RL, LEV and STOP.
“x” is the number related to the measure. For pH setpoint is “1” , for Cl2 is “2”, for mV is “3” and for NTU is “4”.
For example P2A is related to proportional output for Chlorine.
“Channel” is the related output of mainboard connections.

DxA and DxB WORKING MODES.
ON/OFF Mode.
On/Off mode set the instrument to operate using two reading values that enable or disable the related setpoint output.
Parameters to set for this mode are:
ON: Activate RL and LEV on moving towards the unit value (for example: pH)
OFF: Disable RL and LEV on moving towards the unit value (for example: pH)
RL: (choose within available “setpoint output” on mainboard. If an output is already used then it’ll be hided from list.)
LEV: (choose within available “tank level inputs” on mainboard. If an output is already used then it’ll be hided from list.)
STOP: (“ON”: when product into tank is ending, then the related output will be off and an alarm condition will pop-up.
“OFF”: when product into tank is ending, then the related output will continue to stay on and an alarm condition will pop-up.)
ON/OFF mode for reading values “moving up”
Set pH value at 7.00 ON and 6.90 OFF.
Instrument will leave related output active until reading values will increase up to 7.00pH.
At 7.00pH the related output will be disabled until reading value will decrease under 6.90pH.

7.00
ON/OFF mode for reading values “moving down”
Set pH value at 7.00 ON and 7.10 OFF.
Instrument will leave related output active until reading values will decrease up to 7.00pH
At 7.00pH the related output will be disabled until reading value will increase up to 7.10pH.

PWM Mode.
Pulse-width modulation (PWM) of a signal or power source involves the modulation of its duty cycle, to either convey
information over a communications channel or control the amount of power sent to a load.
This mode works over a settable (0 to 100 seconds) time to switch on or off selected output.
Time resolution is 5 seconds, 5 steps. During this time if reading value will move towards a set value (on or off) the PWM
will operate the output on timered basis. Reaching the set value the PWM will permanently leave on or off the output.
Parameters to set for this mode are:
Unit Value + %: (time activity towards set value. 0% means 0 seconds. 100% means 100 seconds.)
RL: (choose within available “setpoint output” on mainboard. If an output is already used then it’ll be hided from list.)
LEV: (choose within available “tank level inputs” on mainboard. If an output is already used then it’ll be hided from list.)
STOP: (“ON”: when product into tank is ending, then the related output will be off and an alarm condition will pop-up.
“OFF”: when product into tank is ending, then the related output will continue to stay on and an alarm condition will pop-up.)
For example: set first pH value at 10.00 = 100% and second pH value at 5.0 = 0%.
For reading values ≥ to 10.00 the output will be permanently ON.
For reading values ≤ 5.0 the output will be permanently OFF.
For reading value of 9.50 the output will be OFF for 10 seconds, ON for 90 seconds.
If reading value decreases to 8.00 then the output will be OFF for 20 seconds, ON for 80 seconds.
fig. 5
10
PID Mode.
A proportional–integral–derivative controller (PID controller) is a generic control loop feedback mechanism.
PID controller attempts to correct the error between a measured process variable and a desired setpoint by calculating
and then outputting a corrective action that can adjust the process accordingly.
The PID controller calculation (algorithm) involves three separate parameters; the Proportional, the Integral and
Derivative values. The Proportional value determines the reaction to the current error, the Integral determines the
reaction based on the sum of recent errors and the Derivative determines the reaction to the rate at which the error has
been changing. The weighted sum of these three actions is used to adjust the process. By “tuning” the three constants
in the PID controller algorithm the PID can provide control action designed for specific process requirements. The
response of the controller can be described in terms of the responsiveness of the controller to an error, the degree to
which the controller overshoots the setpoint and the degree of system oscillation. Note that the use of the PID algorithm
for control does not guarantee optimal control of the system or system stability.
fig. 6
(Kp) is the constant proportional gain
(Ki) is the constant integral gain
(Kd) is the constant derivative gain
(e): error
(t): Time in the past contributing to the integral response
Parameters to set for this mode are:
RL: (choose within available “setpoint output” on mainboard. If an output is already used then it’ll be hided from list.)
LEV: (choose within available “tank level inputs” on mainboard. If an output is already used then it’ll be hided from list.)
STOP: (“ON”: when product into tank is ending, then the related output will be off and an alarm condition will pop-up.
“OFF”: when product into tank is ending, then the related output will continue to stay on and an alarm condition will pop-up.)
ON: Activate RL and LEV on moving proportionally towards the unit value (for example: pH)
OFF: Disable RL and LEV on moving proportionally towards the unit value (for example: pH)
I: integral time (from 0s to 59m:59s)
D: derivative time (from 0s to 59m:59s)
11
PxA and PxB.
Using PxA and / or PxB is possible to control the status of “Proportional pump outputs” based on some parameters.
Refer to “I/O connections” blocks at page 5 to locate these outputs over the mainboard. Once that PxA or PxB function
is enabled (move wheel over “disable” , press, rotate to “enable”, press again to exit) then main parameters are
OUTOPTO, LEV, STOP and pH - PM.
fig. 6
OUTOPTO.
Outopto is referred to “Porportional pump outputs” from “I/O Connections” of mainboard. Set this value between
available outputs. If an output is already used then it’ll be hided from list.
LEV: (choose within available “tank level inputs” on mainboard. If an output is already used then it’ll be hided from list.)
STOP: (“ON”: when product into tank is ending, then the related output will be off and an alarm condition will pop-up.
“OFF”: when product into tank is ending, then the related output will continue to stay on and an alarm condition will pop-up.)
pH - PM
These fields require to set two pH values with pulses for a proportional working mode. This mode let the instrument to
modulate output pulses proportionally to reaching value.
For example: Set first pH to 10.00 with 150PM. Set second pH to 7.00 with 0PM.
If reading value is 10.00 then 150pulses per minute will be forwarded to related output.
If reading value is 7.00 then no pulses will be forwarded to related output.
If reading values are 8.5 then 75pulses per minute will be forwarded to related output.
12
mA1.
Using mA1 is possible to control the status of “mA outputs” based on some parameters. Refer to “I/O connections”
blocks at page 5 to locate these outputs over the mainboard. Once that mA1 function is enabled (move wheel over
“disable” , press, rotate to “enable”, press again to exit) then main parameters are OUTmA, LEV, STOP and pH - mA.
fig. 7
OUTmA.
OutmA is referred to “mA outputs” from “I/O Connections” of mainboard. Set this value between available outputs. If an
output is already used then it’ll be hided from list.
LEV: (choose within available “tank level inputs” on mainboard. If an output is already used then it’ll be hided from list.)
STOP: (“ON”: when product into tank is ending, then the related output will be off and an alarm condition will pop-up.
“OFF”: when product into tank is ending, then the related output will continue to stay on and an alarm condition will pop-up.)
pH - mA
These fields require to set two pH values with mA for a proportional working mode. This mode let the instrument to
modulate mA proportionally to reaching value. mA range is from 0 to 20mA.
For example: Set first pH to 10.00 with 15mA. Set second pH to 7.00 with 0mA.
If reading value is 10.00 then 15mA will be forwarded to related output.
If reading value is 7.00 then no mA will be forwarded to related output.
If reading values are 8.5 then 7.5mA will be forwarded to related output.
13
A1a and A1b
Using A1a and / or A1b is possible to set a visual alarm with delay for values ≥ or ≤ than set value. Once that A1a
or A1b function is enabled (move wheel over “disable” , press, rotate to “enable”, press again to exit) then main
parameters are ALARM and DELAY.
fig. 8

- TO AVOID UNDESIRED MESSAGES USE CAREFULLY LOG SETUP - WARNING: THIS FUNCTION COULD NOT BE FREE OF CHARGE. DEPENDING ON YOUR OPERATOR CONTRACT IT
COULD GENERATE PAYING DATA TRAFFIC !
Modem can be also be used to remotely control the instrument through a communication software.
See “MAX5 PC Communication Software” manual for proper configuration.
GSM SIGNAL STATUS
MAX GSM MODEM VERSION
Before to configure SMS phone number ensure that
internal gsm modem has enough signal to operate
correctly.
Blinking envelope means that MAX5 is trying to
send an alert message to preferred numbers (SMS1
and/or SMS2 and/or SMS3). If this condition stays for
more that 1 minute it could be an error while sending
message. Check modem status or instrument condition.
To check this press
twice from main menu and
verify signal strength as following:
0 or 1 bar (-113dBm to -103dBm)
no signal or very low signal
re-orient
antenna
1 or 2 bars (-103dBm to -95dBm)
low signal
slow conn.
2 or 3 bars (-95dBm to -85dBm)
good signal
ok
3 or 4 bars (-85dBm to -51dBm
or more)
optimum signal
ok
26
Fixed envelope means that MAX5 has successfully
sent an alert message to preferred numbers.
ALARM SETUP
When an alarm condition is displayed and general alarm output is possible to choose between two working modes.
Continuos: alarm condition never stops until “ESC” is pressed.
Timered: alarm condition ends after set time.
fig. 27
LOG SETUP
Log setup stores instrument activities when an alarm (flow, level, general) occurs or after a set time.
fig. 28
Activities can be printed by enabling “PRINT” option. Printer must be RS485 compatible to properly operate.
Data filter option set a delayed time between repeating alarms. This option may be useful to not fullfill memory with
same alarm condition.
Data log example:
001 on 10/09/05 15:36 pH12.06 Cl02.00 D1a=on P1a=150 D1b=off P1b=075 D2=off P2=150 LP1a=Hi LP1b=Hi
LP2=Hi AMD1=OFF AMD2=OFF FLOW=ON STBY=OFF CLEAN=OFF Liter=123456789
PASSCODE
Change default passcode (“00 00”) by rotating wheel on each of two-digits groups. Press “OK” to confirm or “ESC”
to exit without saving. Administrator can also set passcode for “User” with limited access (no instrument reset / mA
setpoint unavailable).

Manual.
Outputs may be activated manually for testing purposes.
fig. 30
“Manual Relay” will activate “setpoints outputs” (see page 4). Exiting from manual mode will revert selected output to its
original condition.
fig. 31
“Manual Pulse” will activate “Proportional pump outputs” (see page 5) with selectable pulses from 0 to 150 for each
ouptut. Exiting from manual mode will revert selected output to its original condition.
fig. 32
