Page 5: Overview
DCM 2 Installation Overview 1.1. All ProMinent DCM2 controllers have an integral web server with an RJ-45 Ethernet connection, ready to communicate with any internet ready computer, regardless of operating system. This makes the ProMinent DCM2 one of the easiest aquatic controllers to remotely monitor and control your pool or spa. - Page 6 Sample and recirculation flow switches are critical safety devices which prevent uncontrolled chemical feed. Follow Instructions Carefully. Flow switches are provided with all ProMinent pool controllers and are an integral safety device to prevent the uncontrolled feed of chemicals, which could cause personal injury or death.
- Page 7 If surge damage occurs, chemicals could be fed to your pool or spa, continuously with no safety controls. If you inspect your ProMinent controller after a possibly damaging power surge (thunderstorm or power outage) and suspect the controller is not operating properly, disconnect the chemical feeders at once, and contact your ProMinent dealer for service.

DCM 2 Installation Water disinfection control involves irritating, corrosive, caustic, and potentially toxic chemicals. Use extreme caution and comply with all national, state and local regulations and recommendations for the handling and storage of these chemicals. System Mounting 2 . 2 WARNING! DO NOT INSTALL YOUR CONTROLLER IN AREAS... - Page 9 Conduit adaptor fittings are available from ProMinent. Refer to local and national electrical codes for wet locations. • Fasten enclosure securely to the bracket as shown, by hanging enclosure on the bracket, pushing the enclosure against wall and lifting until the enclosure snaps securely to the bracket.

NOTE: Keep in mind that a very small sample volume (11-12 GPH) is needed for ProMinent controllers. That is only (0.18 GPM) compared to other aquatic controllers requiring 1-3 GPM. - Page 11 DCM 2 Installation Proper Pressure Filter Arrangement Proper Vacuum Filter Arrangement Page 11...

For applications where the distance from the controller to the sensors exceeds 33 feet, consult your ProMinent distributor for options available to you.
- Page 15 DCM 2 Installation Controller Wiring Terminals DCM2 Controllers consist of two main circuit boards, a main circuit board and an LCD driver board. The main Printed Circuit Board is located in the rear half of the enclosure and supports 3 sensor inputs, 2 digital inputs and 5 digital outputs.

Page 16: 120Vac Line Power And Feeder Wiring
NEVER CONNECT FEEDER DIRECTLY TO POWER SOURCE If the chemical feeders are connected to a wall outlet, the safety devices integral to your ProMinent controller, and to the safe feeding of chemicals, will be bypassed. It is very important that the chemical feeders be connected to the controller and never directly to a wall outlet. -
Page 17: Pulse Controlled Pumps
Pulsed controlled pumps can be connected to give more precise control options like PID control and use low voltage wiring to convey pumping signals to the feeders. These features are built into all DCM2 controllers as a standard feature. Use the diagram below for connections to ProMinent pump universal control cable and similar cables for other pumps. -

DCM 2 Installation 2.3.4. Sensors pH and ORP Sensor Wiring DCM2 controllers normally have the cables for the pH and ORP sensors pre-wired and marked on the cables for the appropriate sensor. The SGT (Solution Ground + Temp) sensor and flow switch are also pre-wired at the factory. If replacing these cables, connect the center pins on the coaxial cables to the positive [+] terminal and the metallic shield is connected to negative [-]. - Page 23 DCM 2 Installation DCM2-Cl (pH + CLB3 Free Cl ) Sensor Connections Page 23...

Users also have the option to manually enter OFFSET and GAIN by selecting Sensor then Configure in the Browser interface, but this is not advised without consulting your authorized ProMinent Service Company. See the DCM2 Browser Manual for more information. -
Page 25: Password Security
DCM 2 Installation 4. Password Security 4.1. Overview DCM2 controllers use 4 levels of password for controller access and to stamp the activity log: Public, Operator, Configuration, and Administrator Refer to Section 4.2 for default user IDs and passwords. Passwords are defaulted OFF for keypad users and ON for Browser users. Passwords cannot be turned OFF for Browser users. -
Page 26: Browser Passwords & Lockout
DCM 2 Installation 4.3. Browser Passwords & Lockout After 5 unsuccessful attempts to log on, the controller locks out Ethernet and Keypad access. Locked out users will see an Alarmed status message in place of Password Incorrect. Browser & modem resets at 7:00AM or when AC power OFF/ON. Therefore, the maximum lockout time is 24 hours and the minimum is less than a minute. -
Page 27: Passwords Reset
Proof of controller ownership is understandably required. ProMinent controllers have no backdoor or super user password. If you forget the password, this is the only way to recover controller access. 5. Application Notes 5.1. -

DCM 2 Installation Notes: Time Modulation control is not advisable when the system response time is faster than 5x the period. In the previous Example; If the measured pH moves from 7.52 to 7.50 in less than 300 seconds (5 Min.), Time Modulation may not hold pH more stable. -

The controller knows the pump’s mL/stroke and maximum stroke rate (Maximum SPM), based on the ProMinent pump model entered, or the values you entered for ‘Other’. Once you select the pump feed method or control mode, the controller sets the optimum Pump Speed. -
Page 32: Technical: Pump Frequency-Stroke Controls
Maximum Feed Rate A pump’s maximum feed rated is its rated maximum strokes/minute x mL/stroke. Example: A ProMinent Beta 1602 pump is rated 180 SPM with a default of 0.24 mL/stroke @ ½ the rated back pressure. The maximum feed rate for this pump = 180 x 0.24 x 60 = 2592 mL/hour, 0.685 GPH, 15.44 GPD At the –70% minimum user adjust: 0.78 L/hour, 0.2 GPH... -
Page 33: Relay & Frequency Controls Comparison
DCM 2 Installation Control Resolution Control resolution = 1mS. 1mS defines the precision of pulsed output variable frequency control. The DCM2 controller calculates pulsed output strokes per minute to the nearest 1000 of a second (1mS), based on deviation from setpoint and other factors like PID control calculations. Example: At 180 SPM, the pump pulses 3 times per second. -
