Dickert Electronic DCM31 - X) Service Mode; Y) Trip Counter

Motor control unit DCM31
27 / 35
- For operation without limit switch, obstruction detection and compliance of the
closing forces must be secured via external safety equipment (photoelectric barrier,
contact strip).
- For operation without limit switch, instead of the usual 4 teaching runs, there are
only 2 teaching runs, as only the running times (for closing delay and onset point
for smooth travel have to be learnt) and the forces do not have to be learnt.
- The limit switch LEDs behind the terminals are only active for operation with
external limit switches. In the other operating modes the LEDs are always off.
x) Service mode
- The menu [M.d8] can be used to secure all menu items against adjustment. In the
delivered condition the menu items can be adjusted.
- [M.d8] can only be adjusted from 0 to 1 and vice versa, in that the emergency stop
is actuated and [Ta.+] and [Ta.-] are simultaneously actuated.
- If the menu items are secured against adjustment, the values of the individual
menu items can be read, however they can no longer be adjusted.
- After installation of the control unit and gate system has been completed, the menu
items should always be secured against adjustment.
y) Trip counter
- [M.d9] can be used to read the number of gate movements (trips in open direction).
- Each start in the open direction is counted.
- Instead of the menu value, the display for menu item [M.d9] shows in the left
display which digit is currently shown in the right (1s, 10s, ..., 100,000s digit). [Ta.+]
and [Ta.-] are used to switch between the individual 10s digits.
- If the display shows e.g. 00, 10, 21, 34, 47, 59, this means the controls have
already carried out (0*100,000 + 0*10,000 + 1*1,000 + 4*100 + 7*10 + 9*1) = 1479
trips in the open direction.
- The trip counter cannot be reset or changed.
