2.5 Remote indicator (optional equipment)
The remote-indicator output corresponds in the same way as the Ready-light unless it is
programmed to indicate e.g. OVERLOAD situation by e.g. an external alarm horn/lamp
(Functional Options 5 and 6). Normally, the remote light is a signal lamp that can be
mounted e.g. on the door of the bridge cubicle.
2.6 Load display
In the load mode CU1 displays the weight of the load as a percentage of the rated
load of the hoist.
A CU1 can be changed into the load mode by pressing the blue push-button once.
By pressing the blue push button once again the display of CU1 returns to the normal
mode.
Example:
A load of 4000 kg on a 5000 kg hoist is displayed as a load value of ca.
L__80 (i.e. 4000 kg / 5000 kg * 100 % = 80 %).
Note that the accuracy of the load sensor is ca. ± 2% with the rated load of the hoist,
but it may be poorer than ± 5% with light loads!
Load display range (unless Err_d displayed):
-Program versions P2.00 - P2.11 -20...120%
-Program version P2.12 - -99...127%
2.7 Error messages
CU1 displays an error message in an abnormal situation due to an
-external failure (sensor, voltage, wiring etc.) or
-internal failure (CU1).
The error messages are presented in Appendix 2.
2.8 Program version
The program version of the CU1 (e.g. P2.12) is shown for 1 second after switching power
on.
