DIAGNOSTIC
The Value 1 Diagnostic screen allows you to view several of the CyberCat 50’s main board monitoring points,
which are supervised continuously. From the Diagnostic Menu 1, press the F2 button to display the Value 1
Diagnostic screen (displayed in an analog-to-digital reference level):

•
Row A (GF) = Ground Fault
< = Level 1 ground fault is active
- = ground fault level is transitioning hardware
> = Level 2 Ground fault is active
For all circuits except RS485 circuits, use the following guides:
Low = 60K ohm or less between power ground and chassis ground
High = 1M ohm or less between Main power (27.6V) and chassis
Level 1<: Low = 0-84
Normal = 85-120
High = 121-255
Level 2>: Low = 0-189
Normal = 190-255
•
Row A (A1) = Voltage Regulator on main for AC power: 120VAC = 200-255, 240VAC = 206-255
•
Row A (L1) = Loop 1 short circuit detect; Normal = 10-255. For all RS485 circuits, the value is 0
ohms.
•
Row B (24V) = Main panel 24VDC power; 140-255
•
Row B (A2) = Voltage Regulator on main for AC power: 120VAC = 200-255, 240VAC = 206-255
•
Row C (B1) = Battery circuit on Main controller: Normal = 80-255
•
Row C (N1) = Notification output #1: Open = 171-255, Short = 49-0
•
Row D (N2) = Notification output #2: Open = 171-255, Short = 49-0

Note:
While trouble shooting a ground fault on panels with firmware Versions 3.0 or later, go into the
Diagnostic screen and the levels are alternating between level 1 (<) and level 2 (>). Find the Level that is
causing the ground and press the ENTER button to lock the level where you are getting the ground fault.
The < or > will flash while it is locked in that level. Press the ENTER button again and the < or > will stay
on steady and begin ground fault detection at both levels again. Pressing RESET will also restore the
CyberCat 50 to auto detect from both levels.
