| How do you trigger an input on the Millenium II? |
DC powered Millenium's require DC voltage be applied to the inputs, and AC powered Millenium's require AC voltage to be applied to the inputs.
100-240 VAC powered controllers input specs:
Pull-In Voltage: 80 VAC or higher (Pull in voltage is the voltage required to turn the input ON when it is in the off-state.
Drop-Out Voltage: 40 VAC or lower (Drop-Out voltage is the voltage required to turn the input OFF when it is in the on-state.
24 VAC Powered controllers input specs:
Pull-In Voltage: 15 VAC or higher
Drop-Out Voltage: 5 VAC or lower
24 VDC Powered controllers input specs:
Pull-In Voltage: 15 VDC or higher
Drop-Out Voltage: 5 VDC or lower
Signals below 15 VDC can be detected with DC powered M2's.
DC powered M2's have inputs that can be configured as analog
or digital. Analog Inputs can be used with a variety of different
sensors (temperature, pressure, strain, etc..), or they can be used
to detect lower voltages than 15 VDC.
Analog Inputs:
Resolution: 8 bits (ADC gives a number 0-255 representing the
voltage applied to the input)
Inputs can be configured for 0-10 VDC sensors or pots 0-24 VDC.
The 0-10 VDC mode can detect a change of .04 volts. A digital
nunber of 0 represents 0 VDC. A digital number of 255 represents
10 VDC. (128=5 VDC 64=2.5 VDC 32=1.25 VDC).

| What power does the controller source from the outputs? |
Millenium II outputs do NOT 'source' any voltage. You have 2 options
for outputs.
1. Relay outputs: 10 amps @ 250 VAC (uL) 8 amps 250 VAC (CE)
On all M2's you have 1 relay with a common, normally open, and
normally closed terminal. All other relay outputs are normally
open(common and normally open terminal).
All relays are dry
contact. These relays are similar to a standard light switch. You
have to wire power to the relay. When the relay closes it transfers
the power on the common terminal to its normally open terminal.
Relay outputs can switch both AC and DC voltages.
2. Transistor Outputs: PNP Open emitter output 700ma @ 28 VDC
Transistor outputs can only switch DC voltages. Transistor outputs
should be used where high cycle rates are needed.
If your load
pulls more than 700ma, or requires AC voltage, the M2 can turn on
a Crouzet Solid State Relay(SSR), which will turn on your load.
Crouzet SSR's are available with current ratings up to 150 amps.
With transistor outputs, like relay outputs, you have to wire the
power to the transistor, it will then source that same power when
your program turns on the output.

Every Monday the controller has stopped. How do I fix this? |
This problem is caused by the cycle time of the controller being too short. The cycle time defaults to 10ms in a Millenium II program. The cycle time is the amount of time the controller will take to scan all inputs, run your program, and update all outputs. On Sunday morning the controller adjusts clock drift and checks to see if it needs to change the clock for daylight savings time. In many cases 10ms is not enough time to to finish all these tasks. The controller then times out because it did not complete the cycle and stops running your program. To fix this the cycle time needs to be adjusted to 20ms. If the problem continues to occur, adjust the cycle time to 30ms.
Steps to adjust cycle time on the Millenium II
1) Open the Crouzet Logic Software
2) Open the M2 program you have created.
3) Click on the box labeled PROGRAM
4. Change the cycle time from 1 to 2
5. Click OK

How do the Analog Inputs work? |
Analog Inputs are available on DC powered units. The input will accept a 0-10VDC analog signal from many different sensors. The resolution of the input is 8 bits. This means the Millenium will 'see' a number between 0 and 255 representing the 0-10VDC span of the sensor. (0 VDC = 0, 10 VDC=255, 5 VDC = 128…) 12 I/O Millenium II's have 4 inputs that can be configured as analog or digital, 20 I/O units have 8 inputs that can be configured as analog or digital. The GAIN function block allows you to scale the 0-255 number from the analog input into units that match your application. Temperature can be displayed in °C or °F, pressure in PSI and so on.

What is a PWM output? |
PWM - pulse width modulation allows a digital output to mimic an analog output. The Millenium varies the on and off time of a square wave proportional to the digital number you give the output. The resolution is 8 bits, so you can feed a number from 0-255 to the PWM output. The lower the number the lower the on-time of the pulse. A number of 0, turns the output completely off, and a number of 255 turns the output completely on. A number of 128 gives a square wave with a 50% duty cycle. This means the on and off times are equal. The base frequency of the square wave remains constant. The base frequency of the Millenium II PWM output can be set from 100Hz up to 2kHz.

|
What is the current rating of the M2 outputs? |
Relay outputs: 10 amps @ 250VAC (uL) 8 amps @ 250 VAC (CE) resistive
Transistor outputs: 700ma @ 28 VDC resistive

| What does the EEPROM cartridge do? |
The EEPROM cartridge is used to transfer programs to controllers. The EEPROM does not add any memory to the controller. It is primarily used by OEM's who want to update programs in controllers they currently have in the field. You have to program the EEPROM with either a SA series contrloller or XT series controller. You first download the program you want on the EEPROM into the controller. Using the menu on the Millenium you will transfer the program in memory on the controller to the EEPROM. You can now send the EEPROM to your customer and using the menu he can transfer the program from the EEPROM into his controller. Units without a display will automatically transfer the program from the EEPROM at power up.

| |
| What can I do with the buttons and display? |
The buttons and display are fully user programmable. The display can be used to show setpoints, or current values of timers, counters, hour meters, analog inputs, or user defined text. The buttons can be used in your programs to do things such as start cycles or reset counters.
|
| |
| How is the controller programmed? |
Programs are created on a PC using the Crouzet Logic Software. Programs are made using function blocks. Function Block Programming is similar to wiring an actual panel of timers and counters, yet much more powerful. Once a program has been created, it can
be transferred to a controller using a Crouzet programming cable. After the program is in the controller it can be sent to EEPROM cartridge to program other M II's.
|
| |
| Can the Millenium II be networked? |
Yes the XT series of Millenium II controllers have an expansion module that allows them to be connected, as a slave to a MODBUS or ASi network.
|
| |
| What is the difference between a local and adjacent extension? |
Local extension plug into the front face of XT20 series controllers. These extension modules do not take up any additional space. Adjacent extensions plug into the side of the controller, and they do take up extra space to the right of the XT20.
|
| |
| How do I panel mount the Millenium II? |
Crouzet offers a faceplate kit for both the 12 and 20 I/O Millenium II's. These allow the front face to be accessible to the user outside the panel.
12 I/O faceplate - 89750103
20 I/O faceplate -- 89750109
|
| |
| What is the maximum number of I/O I can get with the Millenium II? |
With 2 XT20 modules connected via the M2-M2 link modules, and an adjacent expansion of 4 inputs and 2 relay outputs connected to both XT20's you can achieve 52 I/O. 32 Inputs and 20 outputs.
|
| |
| What does the M2-M2 link module do? |
These modules plug into the local expansion port on an XT20 controller. They allow the two Milleniums to communicate with each other. Each controller has 8 digital values that can be read or written to the other controller as well as 3 analogue values. The two controllers can be up to 10 meters apart.
|
| |
| Can the M2 use a modem to call a number in an alarm situation? |
The Millenium II can not be programmed to dial a modem. However, there are several manufacturers of modems that can store a number in the modem. The modem can be triggered to dial that number by closure of a relay contact. The Millenium can be connected to a modem that can be called into. Using the Crouzet Logic Software on your PC you can configure the software to call a remote Millenium II connected to a modem via the programming cable. When the modems connect, you can monitor and edit the program in the controller.
|
| |
| What is the lowest time I can set a timer for? |
The lowest time a timer can be set for is 100ms. All times will be in 100ms increments. You can have a timer set for 1.2 seconds or 2.4 seconds, but not 1.25 seconds, or .05 seconds. It is possible to generate a 20mS timebase, which could be used to create shorter time delays.
|
| |
| What is the fastest frequency the M2 can count? |
Currently the fastest a DC powered controller can count is 33Hz. Coming soon we will have a maximum count speed of 4kHz.
|
| |
| What changed from Millenium I to Millenium II? |
| |
| Physical dimensions of the controller have NOT changed. Just about everything else has. The software and programming cable have both changed. The display is bigger and now has a programmable backlight, and the program memory has doubled. We have also added Custom function blocks like pump rotation archiving and math functions. Sequential Flow Control blocks have also been added. The Millenium II can NOT be programmed from the front face of the controller like the Millenium I. |
