9 .0 TROUBLESHOOTING GUIDE
PROBLEM CAUSE
SOLUTION
Circuit Breaker continuously
trips upon power up.
Mis-wired
Wrong style GFI
Circuit Breaker
Verify with a digital voltmeter that current between L1 &
L2 is below 1 Amp. Wire per section 5.3.
Check that a 3-Wire GFI Circuit Breaker has been
installed.
Circuit Breaker continuously
trips when heaters are
energized.
Wrong size GFI
Circuit Breaker
Replace Circuit Breaker with correct size (See section
5.3)
High Grease Level
continuously activated.
Pump Failure
Solids build up on
grease level sensor
Out of
Calibration
Enter Test Mode and initiate Pump Test (See section 8.6).
- Check for clogged line.
-. Check Fuse (#2) in Controller
-. Check Fuse (XF2) on Interface Board
Inspect the Grease Interceptor compartment for build up
on the level sensor. Clean level sensor per section
7.0.
Enter Test Mode and initiate Water Level Test (See
section 8.6). Reading should approximate level of grease
in the tank. If not recalibration mat be required (see section
section 8.4).
Notify factory for assistance
Difficulty in calibrating unit.
Poor Connection
to level sensor
Verify connection between level sensor and Interface
Board
Temperature Switch LED
continuously on.
Temperature in
GRD above 110° F
Temperature
Switch failure.
To verify, run cold water thru system until temperature
drops below 100° F. NOTE: This process may take approx.
30 minutes.
Meter Upper Thermostat located in electronics
compartment for a short or go to J102 cable on Interface
Board
Level Sensor Failure
Build up around
level sensor
Lost of electrical
connection
Inspect the Grease Interceptor compartment for build up
on the level sensor. Clean level sensor per section
7.0.
Enter Test Mode and initiate Water Level Test (See
section 8.6). Reading should approximate level of grease
in the tank. If not recalibration mat be required (see section
section 8.4).2.
Check continuity from Probe to Interface Board (J101)
using a DVM. Using a DVM with frequency measurement
capability check between Pin 2 and 3 of J101 on the
Interface Board. The frequency should be between 8kHZ
and 30kHZ
