Table 2.3 - Technical specifications of the SY2527 mainframe: input and output signals
(refer to the figure in Appendix A)
VSEL:
Std. NIM/TTL; 00-type LEMO connector.
Function
: channel voltage selection.
ISEL:
Std. NIM/TTL; 00-type LEMO connector.
Function
: channel current selection.
RESET:
Std. NIM/TTL; 00-type LEMO connector.
Function
: RESET from the front panel. If the duration of the RESET signal
is > T
RCPU
=100÷200 ms, the CPU is reset; if it is > T
RCH
= T
RCPU
+ 900 ms,
also the boards are reset and the channels are turned off. Reset must be
enabled via software (RESET FLAG window, see §7.1.22).
KILL:
Std. NIM/TTL; 00-type LEMO connector.
Function
: KILL from the front panel: it turns all channels off.
ENABLE:
Std. NIM/TTL; 00-type LEMO connector.
Function
: remote enable.
INTERLOCK:
open/closed contact; 00-type LEMO connector.
Function
: INTERLOCK command: it turns all the channels off as it is
open/closed, according to the position of the relevant switch.
INPUTS
REMOTE IN:
+12V, 50mA max., electric. insulated;tol.:-40%
÷
+20%;00LEMO connector.
Function
: remote power-on of the system.
OVC:
Std. NIM/TTL (selectable); 00-type LEMO connector.
Function
: at least one channel is in
Over Current
.
UNV:
Std. NIM/TTL (selectable); 00-type LEMO connector.
Function
: at least one channel is in
Under Voltage
.
OVV:
Std. NIM/TTL (selectable); 00-type LEMO connector.
Function
: at least one channel is in
Over Voltage
.
CH-ON:
Std. NIM/TTL (selectable); 00-type LEMO connector.
Function
: at least one channel is ON.
RST FLAG:
Std. NIM/TTL (selectable); 00-type LEMO connector.
Function
: a RESET occurred according to user's settings (RESET FLAG
window, see §7.1.22).
CHK PASSED:
Std. NIM/TTL (selectable); 00-type LEMO connector.
Function
: initial system check successful and system ready.
TRIP:
Std. NIM/TTL (selectable); 00-type LEMO connector.
Function
: at least one channel in
Trip
condition.
GEN:
Std. NIM/TTL (selectable); 00-type LEMO connector.
Function
: GENERAL STATUS indication; corresponds to the logic
combination (defined by the user) of OVC, UNV, OVV, TRIP.
OUTPUTS
REMOTE OUT:
+12V level,refer. to the crate ground;tol.:-20%
÷
+20%;00LEMO connector.
Function
: remote power-on of the adjacent daisy-chained crate.
HVSYNC:
Bidirectional differential signal ; 2-pin LEMO connectors.
Function
: sync clock for the PWS Units ((RS485 Std., 1.25 MHz).
LOCAL NET:
Bidirectional differential signal; 2-pin LEMO connector.
Function
: LOCAL bus for the control of non-intelligent systems ONLY.
CAENET:
Bidirectional CAENET; 00-type LEMO connector.
Function
: H.S. CAENET interface.
I/O
TRIP IN/OUT:
Bidirectional differential signal; 5x2-flat connectors.
Function
: external TRIP lines to handle TRIP conditions.
All the above signals, except for the REMOTE IN/OUT, are referred to a common ground
(COMMON GROUND) and are galvanically insulated up to 150 V with respect to the ground of
the crate (CRATE GROUND).
