VERTICAL CONTACT TOASTER
P/N 1010719 Rev. E 02/13
Conveyor belts are
“jumping” or “snapping”.
(continued).
Temperature display flashes
“LO”.
Temperature display flashes
“HI”.
Conveyor belts installed incorrectly.
Conveyor belt too loose (40 links
required when new). When new, con-
veyor has 38 large links and 2 small
links.
Roller tensioner assy(s). bent or
missing.
Platen temperature is below 420°F
(216°C).
Defective solid state relay.
Heater Platen is “OPEN”.
Faulty control board.
Platen thermocouple is disconnected
or open.
Defective solid state relay.
Platen temperature is over 591°F
(310°C).
Defective control board.
Install conveyor belt to match diagram in
Fig. 17 (page 13). Be sure that ends of the
hooks are facing down.
Remove conveyor belt (page 13). Lay belt
flat and count links. Replace entire belt if
links are damaged. If conveyor belt has too
much play, it will jam. Adjust belt length as
described under Servicing the Conveyor
Belt (page 13).
Replace roller tensioner assy(s). (29, page
26) or tensioners (4, page 30) if damaged
or loose. Replace slide rails (40, page 30) if
worn or missing.
Allow 20 minutes for warm-up and recheck
display.
Replace solid state relay.
To check platen:
Use an Ohm meter to test resistance of the
platen heater (disconnect 1 wire to isolate
heater). Correct cold resistance for heating
element of platen is 17.81 Ohms at
208V/2550 Watts. The auxiliary heaters are
108.2 Ohms at 208V/400 Watts.
Replace control board.
Reattach or replace platen thermocouple.
Replace solid state relay.
See Fault Messages (pages 10 & 11).
Replace control board.
