2.1 Cooling Water
Be sure power to an electronic contactor is turned off when water is turned off.
With a voltage applied, most water will ionize and begin to conduct current between points of
high differential voltages. This current is sufficient to heat the water past the boiling point,
creating steam and possibly causing the rubber hose to burst. The water spraying over the
high voltage circuit can cause considerable damage to the contactor and, most likely, the
control circuitry as well. Never use metallic or other conductive tubing to plumb a water-cooled re-
sistance welding contactor. Heater hose has a very high carbon content and should not be
used for contactor plumbing. A low carbon, reinforced hose (such as the hose originally sup-
plied with the unit), no less than 18" long, must be used to connect the Heatsinks to each oth-
er and to the bulkhead fitting on the inside wall of the cabinet.
The 1200A modular water-cooled SCR Contactor is electrically isolated from electrical circuit
within the contactor section. No minimum length of water hose is required for electrical isolation
of the contactor. It is still recommended to turn power off when control is not in use.
For all water-cooled Heatsinks, be sure water is turned ON before placing welder in operation.
An open drain is recommended for best operation. If a closed return system is used, be
sure return line is properly sized so that back pressure will not reduce water flow be-
low recommendations. A sight flow indicator is recommended.

ENTRON Controls follows the practices of the RWMA for precautionary labeling. See RWMA Bulle-
tins #1 and #5 for a complete description. Observe the WARNING, DANGER, and CAUTION labels
affixed to control to maintain safe operation. ENTRON Controls, LLC. and its affiliates are not re-
sponsible for any harm caused by non-compliance of instructions associated with the aforemen-
tioned labels or signal words to follow.
The signal word DANGER is used to call attention to immediate or imminent hazards which if not
avoided will result in immediate, serious, or personal injury or loss of life. Examples are: exposed
high voltage; exposed fan blades.
The signal word WARNING is used to call attention to potential hazards which could result in
personal injury or loss of life. Examples are: not using proper personal protection; removal of guards.
The signal word CAUTION is used to call attention to hazards which could result in non-life
threatening personal injury or damage to equipment. CAUTION may also be used to alert against
unsafe practices.
The term NOTICE is used for making recommendations on use, supplementary information, or
helpful suggestions. Non-compliance with these recommendations may result in damage to control,
welding machine, or workpiece. ENTRON Controls, LLC. and its affiliates are not responsible for
damage caused by such non-compliance, and warranties may be voided accordingly at the discre-
tion of ENTRON Controls.
WARNING: Individuals with cardiac devices should maintain a safe distance due to strong magnetic
fields arising from resistance welding. The function of cardiac pacemakers and defibrillators may be
disturbed, which may cause death or considerable health damages! These persons should avoid
the welding system unless authorized by a licensed physician.

3.1 Install and Setup
For wall-mount dimensions, refer to the ENTRON Cabinet Guide (doc 780054) on our website.
1. Ensure that all power is removed before connecng the control.
2. Connect the chassis ground to an external earth ground.
3. Connect L1, L2, and H1 as shown in the “CUSTOMER CONNECTIONS” secon of the wiring diagram. An H1 connecon will be
required for each transformer in a mulple-control layout.
4. Using the wiring diagram, verify the T1 jumper connecon properly corresponds with the line voltage.
5. Ensure that all electrical and mechanical connecons are ghtly secured.
6. Connect cooling water as required.
7. Connect any necessary foot switches, valves, E-Stop switches, pressure switches, etc. as demonstrated below.

ENTRON Controls, LLC. 700230D 18
PCB2 TS4
[TIMER V3 OUT] Timer Valve 3 Output (PCB2-TS4-TIMER V3 OUT)
The 24V digital state of P2-4 on the timer module is supplied to this pin. Nothing other than the
V3IN jumper should be connected here; if the connection is unused, then this output should not have a
connection other than V3IN. See TS4-V3IN. With the jumper installed, SV5 will follow the state of
Valve 3.
[V3IN] Valve 3 Control Input (PCB2-TS4-V3IN)
24V digital input used to control SV5. Normally connected to TS4-TIMER V3 OUT. When a jump-
er is connected from TS4-TIMER V3 OUT, the state of SV5 is controlled by the State of V3 and will
mimic the Valve 3 DC output. When required (and V3 is not needed), the jumper between TS4-
TIMER V3 OUT to TS4-V3IN can be removed. The TS4-V3IN input can then be connected to any of
the four programmable output terminals (P2-5 through P2-8) to obtain an AC output that mimics the
programming of the output selected.

[R] AC Solenoid Valve #3 Safety Relay (PCB2 TS7-R)
The valve control relay (CR1) prevents valves SV1, SV3, and SV5 from activating without an initia-
tion on either FS1 or FS2. AC SAFETY RELAY default connection is to JW1. CR1 protection is
applied to the SV5 output. See the warning below.
[B] Bypass AC Solenoid Valve #3 Safety Relay (PCB2 TS7-B)
AC SAFETY RELAY optional connection to JW1. CR1 protection is BYPASSED to SV5 output.
See the warning below.
4.3 Wiring for AC Option
!!! WARNING !!!
This control complies with AWS J1.1:2013 requiring fail safe contacts in series with valve and
weld outputs to prevent spurious outputs. Valve 3 (SV1 to SV5) has a jumper (JW1) that allows
enabling (connected to R) or disabling (connected to B) the contacts from Control Relay 1 (CR1).
This is to allow for programming features that are in the I/O Map when using PCB2-TS4. Thus,
when PCB2-JW1 is in the BYPASS mode, PCB2-TS1-SV5 can turn on independent of the status
of the initiations FS1 and FS2. Care MUST be taken to ensure safe operation.
JW1
!!! WARNING !!!
Installing PCB2-TS7-JW1 to PCB2-TS7-B will BYPASS the Valve Control Relay
(CR1) , which normally prevents valve 3 activation until a weld sequence is initiated.
Since this valve may now be activated without energizing the control relay, care MUST
be taken to ensure safe operation. Please also see the warning below.

5.1 Keypad Functions
KEYPAD FUNCTIONS
The ESCAPE key. Used to return to the previous menu.
The ARROW keys. Used to navigate. If in the menu screens, the down and right arrows
move the cursor/selecon down, while the up and le arrows move the cursor/selecon
up. If in the Status screens, the up and le arrows navigate to the previous Status
screen, while the down and right arrows navigate to the next Status screen.
The ENTER key. Used to select menus and conrm changes to parameters.
The PLUS and MINUS keys. Used to make changes to parameters. If the input for the
parameter to be changed is a number, PLUS will increase the number by one and MINUS
will decrease the number by one. If the input for the parameter to be changed is a menu
of dierent opons, either key can be used to scroll through the menu opons. Holding
the buons down will cause the control to increment/decrement at a faster rate.
The FUNCTION key. Used to navigate from the Status screens to the Main Menu.
Enables weld current. If not on, then an ER35 (Panel no-weld error) is displayed.
