TROUBLE-SHOOTING GUIDE

PROBLEM POSSIBLE CAUSE RECOMMENDED ACTION

UNIT DOES NOT

FILL WITH WATER

(con't.)

Malfunctioning level control

system (con't.)

Disconnect brown and orange wires connected to

VAPOR-LOGIC board terminals 1 & 2 of terminal block

J12. If fill valve does not open, check for proper 24 VAC

(terminals 20 & 21) to fill valve coil. If proper voltage is

not present, the control board is defective.

Check terminals 1, 2, 3 & 4 on VAPOR-LOGIC control

board terminal block J12 for correct voltage:

3 (purple) to 4 (yellow), no water present > 2 VAC. 3

(purple) to 4 (yellow), water present < 0.25 VAC. 2

(orange) to 4 (yellow), same readings as above. 1

(brown) to 4 (yellow), same readings as above.

FILL VALVE DOES

NOT CLOSE

Open drain valve If automatic drain valve is locked in manual open

position, reset to automatic.

Replace valve if there is a broken return spring on the

drain valve.

Clean or replace drain valve if an obstruction in the valve

will not allow complete closure.

Close manual drain valve, if it is open.

If VAPOR-LOGIC shorted output to fill valve coil, replace

board.

Malfunctioning level control

system

Check if probe head is fully plugged in.

If needed, clean probe rod tips.

Verify that VAPOR-LOGIC control board terminal 4 is

grounded.

If there is low water conductivity, add salt to tank water. (I

this solves the problem, consult DRI-STEEM for further

advice.)

Replace board if VAPOR-LOGIC control board is

defective.

Verify that slide switch is set to "AUTO" mode.

Verify that probe is wired correctly.

Check terminals 1, 2, 3 & 4 on VAPOR-LOGIC control

board terminal block J12 for correct voltage: 3

(purple) to 4 (yellow), no water present > 2 VAC. 3

(purple) to 4 (yellow), water present < 0.25 VAC. 2

(orange) to 4 (yellow), same readings as above. 1

(brown) to 4 (yellow), same readings as above.
