Baccara G75-DFC - Differential Filtration Controller Manual

Getting Started

Description

The Baccara Differential Filtration Controller combines a Controller and Differential Pressure Sensor (DP).
Molded DP with three wires cable. Controller with seven wires for valves and sensor interface.
The DFC controller is offered as DC Latch only, and it is suitable for Baccara solenoid Latch 4 ohm.

The controllers operates up to three solenoids. The Controller shows the actual DIF pressure and the pressure SET point. The Flushing Cycle (FC) begins when DIF≥SET appears.

Display

The LCD display shows:

• Actual DIF pressure
• SET point pressure
• FC counter
• Faucet icon displayed whilst FC operating
• Low battery icon appears when battery needs replacing.

Mechanical

• Operating temperature -10ºC to + 60ºC
• Dust and water tight: IP66
• UV protection
• Max. High pressure 14bar/200psi

Electrical

• Power supply: DC unit - 9V battery
• Internal memory retains settings when power supply disconnected.

Mounting

DP: 2"/52mm diameter
2 ft/60 cm. 3 wires cable
High and low pressure ports 1/8"
BSP/NPT male
High pressure port marked on housing.

Connect High pressure before Low pressure. Disconnect Low pressure before High pressure.

Installation instructions

LV9000 - Wire connectors

1. Strip wires ¾" and group bare wires ends together. No pre-twisting necessary with solid wire. Pre-twist stranded wire. If using both wire types, wrap stranded wire around solid wires. See 1A.
2. Insert wires through flexible sealing fingers and bend wires wires into either <V- Channel>.
3. Push inner sleeve into pre-filled outer sleeve until double-locked. Pre-filled silicone fuller waterproofs the connection. Do not reuse connector.

"Dryconn" #22 to #12 AWG

1. Strip wires 13 mm.
2. Align frayed strands or conductors.
3. Do not pre-twist. Place stripped wires with ends even, lead stranded wires slightly.
4. Twist connector onto wires pushing firmly until hand-tight. DO NOT over torque.
5. Swipe excess sealant in and around conductors.
   DO NOT REUSE.

Operating Modes

• Auto
• Off
• FC counter rest
• Manual FC

UD = Upper Digits
LD = Lower Digits

Auto

This mode is the running mode of the controller.

UD shows counter value (see section 3). LD shows DIF and SET values.

Whilst in FC, the faucet icon will turn on and the operating valve number will blink.

Battery icon will blink when low battery is detected:

Display will turn OFF (blank) one minute after no button is pressed (shut off).
Display will turn on with pressing any button.

If DIF≥SET for (n) consecutive measuring samples, FC starts. FC ends one min. after the last valve shut down.

Off

This mode is for OFF season or to stop Auto Mode permanently.
LD shows OFF.

No pressure measuring process occurs Display will shut off as in Auto Mode.

Press MODE shortly (0.5 sec.) to shift the controller Mode from Auto to OFF or backwards.

FC Counter reset

1. From Auto Mode press MODE and together UD will blink with counter content.
2. For RESET, press MODE and together, UD shows c000, then back to Auto.
3. If RESET is not needed, press SET, then back to Auto.

Manual FC

1. From Auto Mode press SET and together, FC starts.
   Display shows "Hand" and "Faucet" icons. VALVE and operating valve # blink.
2. When FC is completed the MODE returns to Auto.
3. To stop Manual FC press SET and together, FC will stop and return to Auto.

Factory Setting

These settings cannot be programmed by the user:

• Pressure units: bar
• FC delay: 2 consecutive readings of DIF≥SET before FC starts.
• Sample Interval time: Auto, as the DIF becomes closer to the SET point, the interval time between samples shortens.
  Max. Interval 60 secs./Min. Interval 5 sec.
• Off time between valves during FC: 20 sec.
• Consecutive FC count number for alarm: 5 count
• Sensor calibration.

Programmable Setting

Valve on Time

Default: 40 sec. range (5 min. 59 sec.) Same time for all valves.

1. To set Valve on Time press MODE until below display appears:
   
2. Use and to adjust seconds.
3. Press SET to continue.
4. Use and to adjust minutes.
5. Press SET to complete setting.

Interval time between FC

Default: A

This interval value will be the max. time between two consecutive FC if DIF pressure does not execute FC.

Range (23 hrs: 59 min. A)

If A is selected, this setting is ignored.

1. To set Interval Time between FC press MODE (one long press), then one short press. The below display appears:
   
2. Use and to adjust minutes. (If A is selected, press SET to complete this setting).
3. Press SET to continue.
4. Use and to adjust hours.
5. Press SET to complete this setting.

Select Valve no.

Default: Valve #1 (Max. three valves)

You have a choice of which # valve will be operated by the controller.

In case of output #1 burnout, you can connect the valve to output #2 and select valve #2 to operate or #3.

1. To select the valve #. Press MODE (one long press, then two short presses. This display appears:
   
2. Use to select valve #1. Valve #1 remain valve #2 blinks. Or use to deselect valve #1. Valve #1 disappears, valve #2 blinks.
3. Repeat the above for valves 2 and 3.

Maintenance

Battery Installation

Replace the battery at the start of each irrigation season and when the low battery symbol appears.

Use a 9V alkaline top quality battery only.

1. Using a Phillips screw driver, remove the four battery cover screws.
2. Remove the battery cover and seal.
3. Replace the battery.
4. After reattaching the seal, put the cover back, and secure with the four screws.
