CAUTION
Be sure to wire the power supply last of all. Touching terminals by
mistake with the power ON might cause an electric shock or
malfunction.
Make sure that the loads connected to the terminals do not exceed the
specified ratings.
Make sure that power of the same voltage and frequency as indicated
on the model number label is supplied to the control.
When configuring control circuits, select reliable timers and auxiliary
relays as necessary for additional functions.
Be sure to ground this control using a lead with a resistance of less
than 100
Ω
, and be sure to ground the burner body.
Bundle power leads, ignition transformer high-voltage cables and flame
detector power leads separately from each other.
Make sure that ignition transformer high-voltage cables are bundled
separately. Keep these cables at least 10cm away from this control.
Connect the blue signal lead from the Minipeeper Ultraviolet Flame
Detector to terminal 5 and the white lead to terminal 6. If the power is
turned ON with the Minipeeper Ultraviolet Flame Detector wired
wrongly, the UV tube might be damaged.
When equipment is restarted after the safety shutoff, check all items
described in Chapter 4, ADJUSTMENTS FOR TRIAL OPERATION.
Before carrying out maintenance and inspection on the burner, be sure
to carry out the pilot turndown test. Carry out this test at least once
every year.
When cleaning the burner, clean the flame detector also.
When mounting or wiring, be sure to follow the instructions in this
user’s manual and manuals provided by the equipment manufacturer or
other device manufacturers.
Follow all applicable regulations when wiring.
Make sure that ignition transformer high-voltage cables are properly
connected to prevent faulty contact. Faulty contacts might generate
high-frequency radio waves, resulting in noise in radios or other
electrical appliances, or causing malfunction.
Connect the ignition transformer ground lead directly to the burner
body, or to a metal part that is electrically connected to the burner body.
