1. Using a knife, cut the diagram out (cut on the outer part of the line).

2. Align the cut-out to your panel and draw cut marks.

3. Cut the hole in the panel to the precise dimensions of the cut-out:
2-11/16 in. x 2-11/16 in. (68 mm x 68 mm)

--> See the installation section for complete instructions.

Thank you for purchasing HM Digital’s PS-200. The PS-200 is a panel mount total dissolved solids (TDS)
controller that monitors and controls levels of TDS in water. The controller has a maximum set point to
help maintain a limit of TDS allowed in the product water, as well as a second sensor to monitor the TDS
level of the feed water. If the TDS level rises to the set point, the controller will activate a warning light,
sound an alarm (optional) and switch the dry contact position from the normal position (to operate a
valve, pump, etc.). Once the TDS level drops below the set point, this will deactivate the light and alarm
and switch the contacts back to the normal position (normally open or closed). NOTE: The IN mode &
sensor does not have an alarm nor control set point. It is a monitor only.

Calibration: Manual by trimmer pot calibration screw
Set-Point: Single point, controlled by on-screen up/down buttons (to any point within the range)
Set-Point Relay: single, isolated, 2A, Max. 220V, resistive load 100,000 strokes
Relay Control (out sensor only): The unit will open or close a circuit via dry contacts when the

ppm level of the OUT sensor (aka product water) reaches or exceeds the control setting (simple
switch). It can be used to control a pump, solenoid valve or other device.
