TunnelWatch System Status Messages in StatWatch

Introduction

Each time the TunnelWatch Data Collector syncs with StatWatch, any TunnelWatch messages are sent to StatWatch. For important messages, StatWatch can optionally send push notifications to StatWatch mobile users, as well as Alerts through the StatWatch web console.

Because TunnelWatch message capabilities are limited, TunnelWatch messages are usually abbreviated and can be difficult to understand. However, when StatWatch receives a message from TunnelWatch, it automatically translates that message into something more detailed and easier to read.

System Status Messages

StatWatch Message

Translated from TunnelWatch Message

Explanation

Conveyor Stopped (Enter switch on but no cars in queue)

ENTER SW ON: NO CARS

 If the field If Enter Switch Is Activated And No Cars Are In The Queue is set to Stop Conveyor or Idle Conveyor, this message will be displayed to show why the conveyor movement was halted.

Conveyor Stopped (No pulse received)

NO PULSE: CONV. STOP

 No pulse was received within the time specified by the Maximum Pulse Time field on the Tunnel Related Inputs screen. This message appears when the Conveyor Movement Monitoring Method field is set to Detect Pulse Switch Failure.

Conveyor Stopped (Roller jammed)

ROLLER JAMMED CONVR.

 No pulse was received within the time specified by the Maximum Pulse Time field on the Tunnel Related Inputs screen. This message appears when the Conveyor Movement Monitoring Method field is set to Detect Roller Jams.

Conveyor Stopped Due To Progress Switch

PROGRESS SW. ERROR

 The conveyor is stopped because a progress error condition was detected.

Enter Switch Bad? (Active longer than max length)

ENTER SW. ALWAYS ON

 The Enter Switch has been on longer than the maximum distance in the Tunnel Related Inputs screen, Length of car before switch failure is reported field.
Troubleshoot the Enter Switch hardware.

Enter Switch Bad? (Tire sw. twice but no enter sw.)

ENTER SW. ALWAYS OFF

 The Tire Switch was activated twice while the Enter Switch was not activated.
Troubleshoot the Enter Switch hardware.

Error: TunnelWatch Queue Is Full

CW / SW PROG ERROR

TunnelWatch is set up for a 2 or more car queue and CarWatch or SiteWatch has attempted to put in too many cars.

This error means that a staff member has attempted to add a vehicle to the TunnelWatch queue when the queue was already full. DRB recommends against using a queue with SiteWatch, that instead the Maximum Queue Length field on the Modify Setup Menu in TunnelWatch should be set to 1.

If the site does not want to set the TunnelWatch queue length to 1 and this message keeps occurring, they need to make their TunnelWatch queue longer.

One Or More TCSs Was Reset

STATION RESET ERROR

 One or more Tunnel Control Station(s) was turned off and back on again.

Progress Switch Condition Detected

PROGRESS SW. WARNING

 A progress error condition is being detected.

Pulse Switch Intermittent

PULSE SW. INTERMITNT

 The Pulse Switch skipped one or more pulses but has since resumed sending continuous pulses. This can affect the tunnel operation if pulses are skipped regularly. This warning should not be ignored. The Lost Pulse counter on the Tunnel Status screen tracks the number of pulses lost.

Simulated Enter Switch Is Active

SIMULATED ENTER ON

 This message is displayed when TunnelWatch is simulating an Enter Switch.
Simulating an Enter Switch prevents down time but does waste utilities and chemicals because it assumes a long car for every vehicle. Troubleshoot or replace your Enter Switch hardware as soon as possible.

Simulated Pulse Activated (No pulse received)

NO PULSE: SIM. PULSE

 TunnelWatch turned on the simulated pulse automatically because no pulse was received within the time specified by the Maximum Pulse Time field on the Tunnel Related Inputs screen.

Simulated Pulse Switch Is Active

SIMULATED PULSE ON

 This message is displayed when TunnelWatch is using a simulated pulse.

SiteWatch To TunnelWatch Interface Not Active

CW / SW NOT ACTIVE

 The interface between TunnelWatch and SiteWatch is set up, but SiteWatch is not sending its regular two-second-status message. This can happen when the SiteWatch computer turns off, including when the midnight reboot happens.
If the SiteWatch computer is on and you're still getting this message, check the physical connections from the SiteWatch computer to the TunnelWatch computer.

Tire Switch Bad? (Intermittent communication)

TIRE SW. INTERMITTNT

 The Tire Switch was only activated once during the length of the vehicle. Troubleshoot the Tire Switch hardware.

Tire Switch Failure

TIRE SWITCH FAILED

 The Tire Switch is always off or always on for the length of the vehicle.
Troubleshoot the Tire Switch hardware.

TunnelWatch Lost Power Or Was Rebooted

POWER LOSS OR REBOOT

 The computer was reset or its power was cycled off.
The TunnelWatch computer went down unexpectedly. Verify that the TunnelWatch computer is getting power and then troubleshoot the computer hardware.

TunnelWatch TCS/RRS Communication Failure

STATIONS:NO RESPONSE

 One or more Tunnel Control Station(s) did not respond to the computer's commands. This can be caused by a conflict in addressing, defective wiring, incorrect connections, or a defective or inactive Tunnel Control Station. The cause is always attributable to a failure in communications between the computer and the Tunnel Control Stations.

TunnelWatch TCS/RRS Communication Intermittent

RRS COM INTERMITTENT

 This message occurs when the success percentage for RRS communications is below 75% but above 10%. Although there is no interruption of normal operation, the communication wiring to each of the Tunnel Control Stations or Remote Relay Stations should be inspected. If this message persists, the Logic board could be intermittent.

TunnelWatch Treated Multiple Cars As One

MULTIPLE CARS AS ONE

 The Tire Switch has been activated more than two times for the length of one vehicle.
If the problem continues, troubleshoot the Tire Switch hardware.

TW Error: Conveyor Has Too Many Cars (20 max)

CONVYR:TOO MANY CARS

The twenty-first vehicle activated the Enter Switch. TunnelWatch can only handle twenty vehicles in the tunnel at the same time.

Have the tunnel entrance staff member send cars into the tunnel farther apart.

TW Hardware Error (Data not being saved)

DATA NOT BEING SAVED

 This error should never occur unless there is a hardware failure in the computer.

TW Reported Vehicle Was Too Long

VEHICLE WAS TOO LONG

 The Enter Switch was activated longer than the Maximum Vehicle Length but shorter than the Length Of Car Before Enter Switch Failure Is Reported. See the Tunnel Related Inputs screen.
If this error message keeps happening, troubleshoot the Enter Switch hardware.

Unknown TunnelWatch Error (Call DRB Systems)

ERROR: CALL DRB SYS!

An unexpected error has occurred. Contact DRB Support.

VPD Sensor Failed

Three consecutive attempts to read the Vehicle Profile Detection sensor have failed.

There may be a problem with the Vehicle Profile Detection hardware. Contact DRB Support.
