Component Features
DELAYED AIR PURGE FEATURES
The control box receives a signal from the gun, once the signal is received the air purge is shut off via the Air Purge
control Valve (APCV), this valve is held in with the Delay Spool Valve (DSV). When the trigger is released the gun sign-
nal is cancelled to the DSV, the DSV then begins to count down to reset mode, once complete the APCV is reset and
air purge resumes.
The DSV is adjustable up to 15 seconds of delay. Factory set point is 2 seconds. To adjust the time delay of the DSV,
remove the plug #7279-09 from cover. Use a small flat head screw driver, turn clock wise to increase delay time, coun-
ter clock wise to decrease delay.
The operator is responsible for recognizing the air purge delay time verses gel time of the materials being processed
with this equipment to ensure the gun does not prematurely set up. The Red eye on the front panel indicates when the
APCV is open, allowing air purge to the gun. The on/off switch will by-pass the signal air to the DSV, allowing the gun
to be operated normally with out the delay action of air purge.
DISPENSE COUNTER FEATURES
The control box receives a signal when the gun trigger is activated, to activate the timer, the timer counter receives sig-
nal from the change over switches. Pneumatic drive systems use a 3 way check valve and receive signal from both up-
per and lower switches, making the timer a “stroke counter”. Hydraulic drive systems use a single signal, typically to
the lower signal switch, making the timer a “cycle counter”.
When the predetermined count is reached the timer activates the bimba cylinder in the back of the gun to overcome
the trigger at the gun, the operator will need to recognize this “feel” of the trigger and release the trigger.
When the gun trigger is released the signal air is cancelled to a delay spool valve (DSV) located in box assembly.
The DSV delays the reset of the counter for 3 seconds.
The timer will reset to the set point and cancel the air to the actuation cylinder.
The on/off switch will by-pass the counter signal allowing the system to operated independent of the counter.
