Page 4: General Warnings
Adequately rated and APPROVED/CERTIFIED power supply cord and plug (supplied by Pulsafeeder), or cable gland suitable for the applicable country is to be attached and replaced by manufacturer’s authorized qualified person or as per applicable local and national regulations Controller is for indoor use only and not suitable for wet location. - Page 5 Drum Levels Three (3) onboard dry contact inputs serve as Drum Level inputs. When a low level is detected the unit will go into an alarm state and the low drum’s identity will be displayed on the screen. The user can program the alarm to deactivate a timer if desired. Drum level #1 is assigned to timer #1, drum level #2 is assigned to timer #2 and drum level #3 is assigned to timer #3.

3. INSTALLATION 3.1 Location Select a mounting location convenient to grounded (True Earth) electrical and plumbing connections. It is recommended that the controller is mounted on a wall or other vertical surface with adequate lighting at a comfortable level. Installation should comply with all national, state, and local codes. -
Page 7: Sensor Installation
3.4 Sensor Installation Conductivity The controller is supplied with a temperature compensated toroidal conductivity probe installed in a tee. The probe should only be installed where adequate flow is going around and through the hole in the center of the probe in the tee provided. pH and ORP When ordered as a pH or ORP model the controller will be supplied with standard pH and ORP probes. -

Page 13: Fluorometer - Trace Chemical
3.13.1 Fluorometer – Trace Chemical The MicroVision EX can be optionally purchased panel mounted with a fluorometer, turner LD2 or Pyxis ST-500 probe. From the factory, the probe comes prewired and calibrated. Alternatively, the probe can be ordered separately, wired and programmed. Be sure to observe the manufacturers wiring directions. -

4.6.2 Digital Inputs 4.6.2.1 Drum Level From the Drum Level menu select how the timer output will respond to a low drum level indication. The available choices are to allow the pump to continue to run, or have the pump stop when its drum level goes low. Drum level #1 is always assigned to timer #1, Drum level #2 is always assigned to timer #2, and drum level #3 is always assigned to timer #3. -

Calibration Allows access to "probe Cal". Download Allows the user to export the data files. Upload Allows the user to import program settings. USB Settings Allows the user to change the USB settings. Factory Reset Restricts access to the factory reset feature. Once the password is set the controller will require a password to access any of the menus. - Page 21 Limit Timer – Set this value to the maximum amount of time the bleed output can stay energized before a Bleed Limit alarm is reported. If the next bleed cycle completes without an alarm the alarm will clear itself on the next cycle. Setting the limit timer value to 00:00 will turn off limiting function of the relay.

Step 2 – Draw a sample of the process flow water and measure the conductivity using a calibrated meter. Be certain the meter being used to measure conductivity is temperature compensated. Do not allow the sample to sit for any length of time after being drawn as this may cause the reading of the sample to be different from the probe. - Page 23 The probe is very sensitive to temperature changes. Allow the probe roughly 5 minutes to adjust to the temperature of the test solution or sample. Calibrating the probe without allowing the probe to equilibrate to the sample temperature could result in erroneous controller readings. 4.7.2.1 pH and ORP Probe Calibration (1 point) Probe Calibration –...

Use proper handling procedures including rubber gloves, eye protection and protective clothing, when handling any acid solution. 7.3.3 Flow Sensor The Flow Sensor uses differential pressure to cause a shuttle to rise and magnetically activate a reed switch. Occasionally this assembly may become fouled, preventing the shuttle from rising and/or falling. -
Page 36: Forseable Misuse
FORSEABLE MISUSE The unit has many relays which can be programmed to operate on a variety of inputs and timers. It is important to verify the system is set up properly through testing, and that relays are actuated by the correct timer or input. It is important to verify all unit readings match a known value. -
