ISSUE:

Timing Mechanism is reporting wrong current

  • Check that the light on the Pump Card is turned on.
  • Swap the Pump Card with a known-working unit.
  • Check the Pump Card for corrosion on the 9-pin connector as well as the solder connector pads on the bottom are free of corrosion.
  • If the issue still exists, the Timing Mechanism should be repaired or replaced.

HOW TO: Check Power Supply Board voltages

Turn off power to the satellite cabinet. This can be done by removing the two fuses located at the bottom of the cabinet. Disconnect the power cables from the Timing Mechanism...

HOW TO: Configure Power Transformers & voltages

There are two types of Power Transformer configurations that were typically installed in a Network 8000 Satellite. Configuration 1. 1 Large Transformer With the Following Connections: 1 black and...

HOW TO: Configure Timing Mechanism address switches

Address numbers range from 1-255 and CSG numbers range from 1-63. To set the address, switch the appropriate dip switches (positions 1-8) in the UP or DOWN position. DOWN repr...

HOW TO: Reinitialize a Timing Mechanism

Many problems with a Network 8000 satellite can be solved by a simple reinitialization of the Timing Mechanism. This process clears all the memory and operating parameters of the Timing Mechanism and often...

HOW TO: Verify a Timing Mechanism address

Navigate with the arrow buttons to the "CONFIG", "REVIEW" menu and then select "SAT. ADDR." to display the address settings in the right-hand display window. If the address shown...

ISSUE: Power Supply Board indicator light(s) off, dim, or too bright

This indicates that the voltage(s) associated with the indicator light(s) is/are not correct. This can be caused by a bad Power Supply Board, or by an overload condition originating in the...

ISSUE: Pump Card light is off

In most instances where the Pump Card light is off with station power on, the Pump card may still be operating normally. There may not be a problem unless you are experiencing additional Pump Card-related issues such as...

ISSUE: Pump is not turning on

Check that the light on the Pump Card is turned on. Check for corrosion on the 9-pin connector as well as the solder connector pads on the bottom are free of corrosion. Swap the Pump Card with a known working Pump Card.

ISSUE: Single station is not turning on or is stuck on

Check the 6-pin connector for corrosion on the pins. Check the output contacts on the bottom of the board are free of debris and corrosion. Problem may be related to the Timing Mechanism...

ISSUE: Sprinkler heads not turning on

Check that the light on the Pump Card is turned on. Check for corrosion on the 9-pin connector as well as the solder connector pads on the bottom are free of corrosion. Swap the Pump Card with a known working Pump Card.

ISSUE: Timing Mechanism is beeping, repeating two short beeps, or displays are not working

Any of these symptoms may indicate a Timing Mechanism internal failure, but they can also be caused by other problems in the cabinet: mal...

ISSUE: Timing Mechanism is dead or exhibiting abnormal behavior

Check the Power Supply Board lights. Each of the four lights should be on and have fairly equal intensity. Mismatched light intensity indicates a problem with one or more Power Supply Board voltages.

ISSUE: Timing Mechanism is not communicating with the central computer

If the trouble is occurring with multiple satellites in an area, the problem may be in the field communications wiring or the Central Comm Surge Board. If you have determined the issue...

ISSUE: Timing Mechanism is repeating a series of three or four short beeps

These are error codes that indicate a Timing Mechanism internal failure. As such, the unit should be repaired or replaced.

ISSUE: Timing Mechanism is resetting when output stations activate

Check the Power Supply Board voltages, paying particular attention to the voltage on pin 6. Voltage testing instructions can be found here. If the Power Supply Board is known to be working...

ISSUE: Timing Mechanism keypad wheel functions are not working

This issue generally results from a failed keypad or an internal failure within the unit. In either case, the unit should be repaired or replaced.

ISSUE: TRIAC Board is not turning on

This issue is normally caused by a problem with the Distribution Board (if so equipped). Check the fuses in the Distribution Board, replace if available (0.5 Amp Slow-Blow). Check fuse retaining brackets for corrosion. Check TRIAC connector...

ISSUE: TRIAC Board switches are stuck

Unfortunately, if the switch(es) cannot be brought back via lubricant, the unit must be repaired or replaced with a new one.
