Halogenated Hydrocarbon Solvent Hazards
Do not use halogenated hydrocarbon solvents in a pressurized system that
contains aluminum components. Under pressure, these solvents can react with
aluminum and explode, causing injury, death, or property damage. Halogenated
hydrocarbon solvents contain one or more of the following elements.
Element Symbol Prefix
Fluorine F “Fluoro-“
Chlorine Cl “Chloro-“
Bromine Br “Bromo-“
Iodine I “Iodo-“
Check your material MSDS or contact your material supplier for more
information. If you must use halogenated hydrocarbon solvents, contact your
EFD representative for compatible EFD components.
High Pressure Fluids
High pressure fluids, unless they are safety contained, are extremely hazardous.
Always release fluid pressure before adjusting or servicing high pressure
equipment. A jet of high pressure fluid can cut like a knife and cause serious
bodily injury, amputation, or death. Fluids penetrating the skin can also cause
toxic poisoning.
Warning: Any injury caused by high pressure liquid can be serious. If you are
injured or even suspect an injury:
• Go to an emergency room immediately.
• Tell the doctor that you suspect an injection injury.
• Show the doctor this note.
• Tell the doctor what kind of material you were dispensing.
Medical Alert–Airless Spray Wounds: Note to Physician
Injection in the skin is a serious traumatic injury. It is important to treat the injury
surgically as soon as possible. Do not delay treatment to research toxicity.
Toxicity is a concern with some exotic coatings injected directly into the
bloodstream.

Input/Output Connections
The 10 pin terminal strip includes a 5-24VDC and contact closure CC initiate
inputs. Outputs include an Alarm Out, End of Cycle EOC and a 24VDC courtesy
power.
5-24 INIT: Dispense initiate input activated with a 5-24VDC input voltage.
EOC OUT: End-of-cycle feedback
ALARM OUT: Circuit that closes when an alarm condition is present.
CC INIT: Dispense initiate input activated with a contact closure switch.
24VDC OUT: Courtesy output 24VDC, 100mA.
Note: ALARM OUT and EOC (End-of-cycle) only function in RUN mode.

20
Initiate Connections
The 7140 can be initiated by three inputs:
1. 5-24 INIT: Application of 5-24 VDC to the 5-24 INIT terminals, pins 1+2.
2. CC INIT: Application of mechanical contacts on CC INIT terminals, pins
7+8
3. Foot Pedal: Use of Optional EFD foot pedal (part number 7016714) plugged
into foot pedal receptacle.
A connection schematic is detailed on page 21.
Alarm OUT Connection
The ValveMate 7140 features an alarm output circuit. The Alarm OUT circuit
closes when an alarm condition is present. The Alarm OUT circuit is a normally
open electronic switch that can switch an external 5-24 VDC circuit to an external
signaling device or PLC input. Maximum load is 100mA, 5-24 VDC.
Alarm IN Connection
The ValveMate 7140 offers an alternate use of the CC INIT initiate input for an
external alarm signal. Refer to the ʻHow toʼ instructions on page 15 to enable.
When enabled as an alarm input the CC INIT on pins 7 and 8 is connected to a
normally closed switch such as a low level reservoir float switch. When the CC
INIT is enabled as an alarm input the connections on pins 7 and 8 must be
closed to initiate a spray valve cycle.
End of Cycle Connection (EOC)
The ValveMate 7140 features an End-of-Cycle (EOC) circuit to acknowledge an
active spray valve actuation cycle. The EOC circuit is a normally closed
electronic switch that can switch an external 5-24 VDC circuit to an external
signaling device or PLC input. Maximum load is 100mA, 5-24 VDC.
End of Cycle (EOC) signaling only functions when the ValveMate 7140 is in the
RUN mode. The End-of-Cycle (EOC) is normally closed in RUN mode while
spray valve cycle is inactive. The EOC switch opens when the spray valve
cycle is initiated and closes when the spray valve actuation cycle is completed.
The EOC signal only represents the spray valve actuation time and is not
affected by the spray valveʼs nozzle air delay time setting.
24 VDC Output
Courtesy 24 volt DC 100mA can be used to provide power to EOC and Alarm
out circuits for signalling purposes. Also, can be used as a power source for an
indicator device or initiate signal through a contact closure switch to the 5-24
INIT circuit.
