Chapter 5 Connecting Customer-Supplied Safety and Power Control Equipment to the CIP
Adept MV Controller User’s Guide, Rev. B 107
• Timing: the High Power signal transition will be seen only if the signal is
off at least 32 milliseconds followed by on for at least 32 milliseconds.
After a positive transition, there must be no positive transitions for at
least 2 seconds before another positive transition will be recognized.
Remote High Power On/Off Lamp
The CIP High Power On/Off Lamp will cause a V
+
error if the lamp burns out.
This error prevents High Power from being turned on. This safety feature
prevents a user from not realizing that High Power is enabled because the High
Power indicator is burned out.
This feature can be added to the Remote High Power lamp as well. A jumper
must be installed on JP2 inside the CIP. See 53!
*"# for details on accessing the JP2 jumper. The Remote
High Power lamp current limitations are:
Maximum current, 300mA at 5V.
Minimum current, 100mA if JP2 is installed. Otherwise, there is no minimum
current.
The third pair of pins, which provide for more restricted operation, complying
with the EN 775 recommendation, will prevent the use of the “Central Control
High Power On/Off” when the system is in Manual Mode. This function will
work only when the keyswitches on the CIP are in the following positions:
• Operating keyswitch is in the Automatic Mode
• Control keyswitch is in the NET position (|)
The user-supplied voltage to provide a “Central Control High Power On/Off”
function drives a relay in the CIP with the following electrical characteristics:
• Coil: 24 VDC at 1440 Ω, including a parallel “flyback” diode.
• Timing: the High Power signal transition will be seen only if the signal is
off at least 32 milliseconds followed by on for at least 32 milliseconds.
After a positive transition, there must be no positive transitions for at
least 2 seconds before another positive transition will be recognized.
Connecting the System Power Switch to the CIP
The CIP also provides a connection for a user-supplied system power circuit (see
'(, '(, 94 % (, and 94%( for the customer system power
switch circuitry).
