3.1 Syscon circuit Note:
• When perform this adjustment, remove the Mechanism
assembly.
3.1.1 Timer clock
Signal (A) • No signal
Mode (B) • EE
Equipment (C) • Frequency counter
Measuring point (D1)
Short point (D2)
Adjustment part (F) • C3025 (TIMER CLOCK)
Specified value (G) •1024.008 ± 0.001 Hz
(1) Connect the frequency counter to the measuring point
(D1).
(2) Connect the short wire between the short point (D2) and
Vcc (5V).
(3) Short the leads of capacitor (D3) once in order to reset
the microprocessor of the SYSCON.
(4) Disconnect the short wire between the short point (D2)
and Vcc then connect it again.
(5) Adjust the Adjustment part (F) so that the output fre-
quency becomes the specified value (G).
