2. The primary input of the transformer should be protected by
Metal Oxide Varister (MOV) surge suppressors, supplied
with the IB. For protection from electrical transients, con-
nect one MOV between one leg of the input voltage (high
side) of the 24 VAC transformer and earth ground. Connect
a second MOV between the other leg of the input voltage
of the 24 VAC transformer and earth ground. See Figure 2.
3. The pumpdown terminals must be supplied with a “dry”
contact from a switch or relay. No external power should be
applied to these terminals.

ORDERING INFORMATION

terminal strip across the bottom.
+4-20 -
connection for the positive leg of a 4-20
milliamp or 0-10 volt signal

connection for negative leg of a 4-20
milliamp or 0-10 volt signal

black wire from valve, or both valves when
two valves are used

white wire from valve, or both valves when
two valves are used
G -
green wire from valve, or both valves when
two valves are used
R -
red wire from valve, or both valves when two
valves are used
IN -
from external pumpdown switch or relay.
See wiring instructions.
GND -
to external pumpdown switch or relay.
See wiring instructions.
24V-1 -
from 24 volt, 30 VA or 40 VA transformer.
See wiring instructions.
24V-2 -
from 24 volt, 30 VA or 40 VA transformer.
See wiring instructions.
NOTE:
Power supplied may be 24 volts AC or DC.
Note:
The terminals are labeled IN and GND. The GND termi-
nal is shared with the grey ESX wire. Do not connect GND to
system ground.
OPERATION and TROUBLESHOOTING
When properly configured and installed the IB Series requires no
maintenance. They incorporate a number of operational features
to assure trouble free service. On power-up the board will ini-
tialize by giving the valve a large number of steps to assure that
the valve is fully shut. The routine will require approximately 8
seconds for the IB1, 11 seconds for the IB ESX, 16 seconds for
the IB2 and IB3, and 32 seconds for the IB6. The valve will not
respond to input signals during this time.
If the valve is required to shut during operation, the pumpdown
terminals should be used. When given a pumpdown signal, the
board will shut the valve immediately and overdrive by 250 steps
to reset most valves’ position and 50 steps for ESX valves. On
removal of the pumpdown signal the valve will resume position
as dictated by the external control signal.
If power is lost to the IB or wire to the valve severed, the valve
will remain in its last position. Solenoid valves may be desired
before the step motor valve on critical applications.
To force the valve shut during operation for test purposes, simply
remove the jumper from CN4 or CN3, depending on configura-
tion. To resume normal operation, replace the jumper.
To allow for component tolerances, the IB will shut the valve
when the input signal reaches 4.05 milliamps or 0.05 volts
depending on the configuration.
The IB can power one or two valves (IB-ESX can only power
one ESX valve). The valves will operate simultaneously and will
open and close by the same number of steps. Valve wires must
be connected exactly the same for both valves.
