Testing Limit switches
With grill in off position
1. Press green button to lower platen.
• When platen lowers the upper limit switch LED on the
SIB will change state.
• When platen stops at home position lower limit switch
LED should change state.
2. If the platen passed lower than the switch but does not
stop then this is due to the UI not seeing an Encoder
count the platen will now continue until it presses the
lower kill switch.
Check Hood Height
1. Go to hood height settings from the settings menu.
2. Enter hood height settings.
a. Press on Platen current position box and enter the
maximum value allowed.
i. Depending on software this could be 4600 or 5200
ii. We recommend 4850.
3. The platen will rise and then stop but the RED DOT will
stay coloured.
4. Read the value of platen current position.
a. Eg value may say 4637 mils.
5. This is your maximum hood height before touching the
kill switch.
6. Deduct 100 mils from this value and that is your
maximum Hood height value for that lane.
7. Set the new value in the hood height setting and press
apply then end calibration.
Testing kill switches
1. To check the upper kill switch complete section 1 – 5 of
“Check hood Height” this proves the upper limit switch
position.
2. To set the lower switch enter Gap calibration.
3. Once you have entered the gap calibration to the point
that you are able to control the platen height set the
platen position to -100.
4. The platen should be able to reach the value. If it stops
before the platen drives to -100 mils then the Lower kill
switch is incorrectly positioned.
5. Readjust the lower switch position and complete steps
3-4.
Motor Over current (E2 Error)
Check your SIB version Revision N or higher are newest spec
Revision M could cause and issue when fitted with a Norgren
Actuator.
1. Drive the platen up and down.
a. Whilst doing this check the LED on the SIB that shows
over current (E2).
b. NOTE:
If this flashes red then the platen is drawing
excessive current (it may happen under normal
circumstances on initial movement or as the platen
starts to angle.
2. If this flash is consistent it could be the platen shaft is dry
and need lubrication.
a. Remove platen arm to expose shaft carriage block.
b. Remove the 3 ¼ bolts holding the shaft seal gap.
c. Remove the 2 bolts that hold the platen shaft to the
actuator.
d. Remove the actuator clevis pin.
e. From the top now lift the platen shaft.
i. It should separate and come out of the bearing with
the shaft seal still attached.
f. Clean the grease and carbon from inside the bearing
and the shaft.
g. Now apply Nevastane – XMF grease inside the shaft
tube bearing. Ensure you cover the top and lower
bearings
i. You
can not
use the following:
01. Thin spray Grease.
02. WD40.
03. Shake Machine Lube.
3. Now you need to reassemble the grill.
4. When reinserting the shaft in the bearing make sure you
lower it and rotate the shaft to spread as much grease as
possible.
5. Do not tighten the 3 x ¼ bolts that hold the shaft seal cap
on until the platen arm is refitted.
6. Once reassembled run 5 times up and down then review
step 1.
7. If the grill still shows excessive current and triggers the
Error 2 message, then replace actuator.
