5.2.5 Failsafe Configuration
The CP-60 is factory set in a failsafe configuration. This means that if power is disconnected to the unit, or the relay fails
to properly engage, it fails in such a way that it is in the alarm position. ENMET recommends leaving the relay in a failsafe
configuration. However, relay 1 – 5 can be re-configured by using the following procedure.
To change a relay failsafe configuration you must enter the maintenance menu. Press the OPTION switch until “Enter Maint
Menu” is displayed then press SELECT switch for the Enter Password menu. Enter the valid password as described below.
In the " Enter Maint Menu " position
Press the SELECT switch " Enter Password
❚
0 " is displayed. Press SELECT switch once, to move cursor to next digit,
this will be the first digit of the password.
In the
❚
000 position, the underline cursor is under the left digit.
Press the OPTION switch to change the left digit; select the correct digit.
Press the SELECT switch, which locks the digit in place and moves the cursor one digit to the right.
Continue this process until the four-digit password is complete. When a valid password is inserted in this manner, the
display is transferred to the "
Calibration " portion of the menu. If an invalid password is inserted you are returned to the
Enter Maint Menu display.
After entering a valid password:
