Wyvern Timer 2000R Operating Instructions
Secondary Output ON/OFF Time
Equipment controlled by the Wyvern Timer 2000R may require a secondary output to continue
running following the end of the timed operation (for example a fan operated cool-down period).
The secondary output program codes only allow you to set this time in minutes and seconds.
During the run-on period the display may flash ‘Cool’, depending on how program code 25 has
been set. Additionally by selecting program code 3002 coin lockout may be activated during
cool down.
Further options include the use of program code 27 to allow the secondary output to be
switched ON or OFF during the start delay or pre-time, and program code 28, which allows
the keyswitch to control the secondary output operation.

Secondary Output Time Programming Codes
Additionally to the options described above special option program code 01 (see page 27)
determines whether the secondary output remains on or turns off when the external stop, or
optionally fitted emergency stop switch, is pressed. With special option program code 01 set to
OFF (default factory setting) both the main and secondary outputs turn off and all remaining
time is cancelled. If special option program code 01 is set to ON only the main output turns off
and the secondary output remains running for the time determined by program codes 02 and
03. The external input must be enabled with program code 26 (see page 24).
