performs an extensive system of checking values and parameters. All of the operating parameters are stored in non-volatile memory, without the need of a battery. 4.1.4 The Model 2200P operates like a normal analog converter with a number of additional functions made possible by the microprocessor in the instrument.
the Normally Open contact. In the event of power loss to the unit, the relay will deenergize and the device connected to the Normally closed contact will be turned on. This option is selected with the DIP switches on the swing out board. See Section 4.7. 4.4.5 An option provides cycling for Relay A and Relay B to obtain closer process control. When the process is between the relay on and relay off setpoints the relay will cycle on and off, based on the cycle times selected by the user.
4.6.4 When in the menu mode, the display initially shows the current value of the parameters, such as the setpoint of the control relay, while putting all of the outputs on hold. The two arrow buttons are used to adjust the display value up or down. To accept the new value press ENTER twice. While the value on the display is being changed, the relay outputs and the analog outputs remain on hold.

• Set Control Relay B Relay Off Setpoint at 7.50 pH With the above configuration Relay A will control the addition of caustic. The caustic pump will turn on if the pH falls to 6.00 pH and will stay on until the pH rises above 6.50. Relay B will control the acid pump. The acid pump will turn on if the pH rises to 8.00 pH and will stay on until the pH falls to 7.50. Therefore the pH will always remain between 6.00 pH and 8.00pH 5.9 Cycle Feature for Relays A and B 5.9.

It is a single point calibration at 25°C. If needed, this calibration can be repeated as follows: a) Disconnect the temperature sensor wires from terminals BK and YL on TB2. b) Enter the Utility Menu, as described in 7.2.1.
7.6 Adjust 0-1 mA / 0-5 Vdc Output 7.6.1 It may be desirable to fine tune the 0-1 mA / 0-5 Vdc output to take into account the characteristics of your particular loop. The following method involves a high and low calibration and requires the use of a digital multi-meter. (DMM). Proceed as follows ignoring the instrument display: a) Turn off the power to the instrument. Connect your DMM in parallel with the 0-5 Vdc output terminals on the power supply board. b) Turn on the power.
8.1.1 The 2200P has diagnostic features which alerts the operator to invalid entries and memory loss. Invalid entries are indicated by the flashing of the appropriate menu LED. The flashing will commence after RUN is pressed and will continue until the errors are corrected. Memory loss is indicated by the flashing of TEST and by the alarm relay if enabled by DIP Switch No. 5 of Bank S1. See Section 4.7.3. 8.2 Invalid Calibration 4.8.
these steps do not solve the problem it may be necessary to replace the power supply board. See Section 9.4 below. 9.2.3 Should your process control element e.g. pump, valve or alarm not be activating, check that the correct power is supplied to the "floating” relay contacts, jumped over from the line voltage terminals or perhaps from a separate breaker or DC supply. Use the TEST menu feature to simulate the input values to observe the switching points.
case of a memory loss problem, when so advised by AquaMetrix service support. 9.3.3 Before performing the "ESCAPE" procedure it is important to know that this procedure provides the option to erase all programmed values and replace them with the factory set default values. This is true for the control relay on and relay off setpoints, the alarm settings and the analog outputs scaling. Also, the temperature and the pH calibration points will be set to their initial values.
b) The power supply circuit board is fastened to the back of the enclosure by four screws, remove the screws and the board is free. Reverse the procedure to mount a replacement board. c) The microprocessor circuit board is located on the swing-out assembly behind the door. Swing the assembly out, lift it up to unseat the lower hinge pin (the upper hinge pin is spring loaded.) The assembly is now free. The circuit board is fastened to the front panel by five screws.
