INCORRECT INSTALLATION
•
Both SMs sensors should detect the presence of the tool when it reaches the botton
dead center of the press to start a muting sequence. The second sensor SM2
effectively starts the muting sequence. If the first sensor SM1 is released before the
tool reaches the bottom dead center, the re-activation of this sensor during the opening
stroke stops the muting sequence, and the intrusion of an object inside the safety light
curtain detection field stops the press (see figure 3.9).
•
The EMs sensors should detect the tool when it reaches the top dead center of the
press. The first sensor EM1 effectively stops the muting sequence. If the second sensor
EM2 is not activated when the tool reaches the top dead center, the next muting
sequence is not allowed, and the intrusion of an object inside the safety light curtain
detection field stops the press.
INCORRECT INSTALLATION
•
The positon of the second sensor SM2 must be adjusted so that the SM2 sensor is
activated when the press tool reaches the bottom dead center (or when the press tool
reaches a position at 6 mm above the bottom dead center).
•
Do NOT mute the light curtain during the closing stroke of the press
Failure to comply with these instructions could result in death or serious injury.
SENSORS COINCIDENCE TIMING (tmax) AND MUTING DURATION (
∆
max)
•
Both sensors SM1 & SM2 must be activated within a preset time frame 8 ms < t <
tmax. The setting of the timing tmax also sets the muting maximum duration
∆
max : select the
tmax timing corresponding to the shortest muting duration
∆
max allowing the operator to
carry out the manual operation (refer to chapter 2.4.2 SM inputs).
•
On a press, both limit switches must be activated within the following time frame : 8
ms < t < 1s. The maximum duration
∆
max of the muting sequence must be set to 1 mn.
These settings are available on delivery.
Failure to comply with these instructions could result in death or serious injury.
